The BF-88ST is a cost effective FRS radio. It can communicate with any other brand of radio that with FRS frequency, but without spending an exorbitant amount of cash! You just need to make sure they are in the same channels/frequencies, and this can be simply checked by using the software. If they are not in the same frequency, just program via computer. (See chapter "Computer Programming")

Battery Save Function

This function can be set by the software.
By turning on this function the standby time can be much longer.

Busy Channel Lockout

You can turn on/off this function via software.

1. If the current channel does not have CTCSS/DC, when there is a signal, TX prohibited when you press PTT.
2. If the current channel does not have CTCSS/DCS, when there is signal which does not have CTCSS/ DCS, TX prohibited when you press PTT.
3. If the current channels does not have CTCSS/DCS, when there is signal which have CTCSS/DCS, the radio will transmit when you press PTT.

VOX

Turn VOX on/off though the software or special key combinations. Speak to the microphone in normal voice to transmit, no need to press PTT switch.

1. When VOX is on in your working channel: Speak to the microphone directly, it will transmit automatically.
2. When a headset with a microphone is used: When VOX is on, you should VOX again for the radio to identify voice volume.

If the microphone is sensitive enough, the radio will start transmit.
If the microphone is not sensitive enough, the radio cannot collect your voice. Please adjust your voice volume to guarantee smooth communications.

Voice Prompt

1. The voice prompt can be selected to "ON/OFF" through the menu voice/Beep Tone of the "Optional Feature" in the software. When choosing OFF, voice prompt turns off.
   
2. Channel annunciation: You will get to know the working conditions of current channel which is being operated.
3. Low battery alert: The radio will remind you when the battery capacity reaches the minimum operating voltage.

Low Battery Indication

When the radio is in transmitting or standby, if the battery capacity reaches the predetermined low level, the indicator light blinks red, and a low battery alert tone will be heard. The indicating tone will be "Please change the battery". When the low battery alert occurs it cannot transmit, please change or charge the battery.

Squelch

The squelch level will determine the signal strength at which the radio speaker is turned on. If the squelch level is low, the background noise of the radio speakers will be higher, the corresponding communication range will be further, but the anti-interference ability will be weaker.
The default setting of squelch level is 5. You can adjust it through the menu "Squelch Level" in the software from level 0 to 9, and 0 is the lowest level.

Time-Out-Timer (TOT)

This feature provides a safety switch that limits transmission time to a programmed value. This will promote battery conservation by not allowing you to make excessively long transmissions, and in the event of a stuck PTT switch it can prevent interference to other users as well as battery depletion. If the transmitting time exceeds the TOT preset time, a beep will be heard and the radio will stop transmitting.

QT/DQT (CTCSS/DCS)

QT/DQT (CTCSS/ DCS) is the sub-audible signaling, to prevent the radio from receiving unwanted signals on the same frequency. When CTCSS/DCS is set, then within the communication range, you can only receive signals from the same frequency with the same QT/DQT setting. When the QT/DQT is off, you will get all the signals from the same frequency within the communication range.

CTCSS

DCS

Side Key Custom Setting (Monitor/Alarm)

You can custom the second side key as Monitor key or Alarm key by programming in the CPS software.
Click Edit > Function Setting, under "Side Key", you can activate 3 optional functions: "Off means side key function is unavailable "Monmome" means Monitor function, "Alarm" means Emergency Alarm function.

Monitor

This feature allows users to check whether a channel is clear before transmitting. If a frequency is in use, you can hear what is transmitting. If s important to check the frequency and privacy code you intend to use and select clear frequencies to set your channels.
If s also helpful to use the radio when receiving a weak signal. Press and hold MONI button, the indicator light will turn green which indicates the radio is receiving signal.

Emergency Alarm

Emergency Alarm is used to indicate an emergency situation. When press and hold the Alarm key, it makes a loud alarm so that other people will know you are in trouble. You can initiate an emergency call at any time, even if there is activity on the current channel.

RF Energy Exposure and Product Safety Guide for Portable Two-Way Radios

ATTENTION!
Before using this radio, read this guide which contains important operating instructions for safe usage and RF energy awareness and control for compliance with applicable standards and regulations.
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to, sunlight and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly, can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop standards for safe exposure to RF energy. These standards provide recommended levels of exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection.
All BAOFENG two-way radios are designed, manufactured, and tested to ensure they meet government established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of two-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it.
Please refer to the following websites for more information on what RF energy exposure how to control your exposure to assure compliance with established RF exposure limits: http://www.who.int/en/

Radio License

Governments keep the radios in classification, most of the classified walkie-talkie needs to get local government License and operation is allowed. For the following specified classification: the USA FRS, Australian CB, the individual license is not required.

RF Energy Exposure Standards and Guidelines (If appropriate)

Your BAOFENG two way radio complies with the following RF energy exposure standards and guidelines:

1. United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR part 2 sub-part J.
2. American National Standards Institute (ANSI) institute of Electrical Electronics Engineers (IEEE) c95.1-2005.
3. IEEE Std. 1528: 2013 and KDB447498, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
4. Institute of Electrical and Electronics Engineers (IEEE) C953-2002.
5. International Commission on Non-Ionizing Radiation Protection (ICNIRP).
6. Ministry of Health (Canada) Safety Code 6& Industry Canada RSS-102.
7. International Electrotechnical Commission IEC62209-2. 2010.

Operating Instructions

1. Transmit no more than the rated duty factor of 50% of the time. To Transmit (Talk), push the Push To Talk (PTT) button to receive calls(listen), release the PTT button. Transmitting 50% of the time, or less, is important because the radio generates measurable RF energy exposure only when transmitting in terms of measuring for standards compliance.
2. Transmit only when people outside the vehicle are at least the recommended minimum lateral distance away from a properly installed according to installation instructions, externally mounted antenna.
3. When operating in front of the face, worn on the body, always place the radio in a BAOFENG approved clip, holder, holster, case, or body harness for this product. Using approved body worn accessories is important because the use of BAOFENG approved accessories may result in exposure levels, which exceed the IEEE/ICNIRP occupational/controlled environment RF exposure limits.
4. lf you are not using a body worn accessory and are not using the radio in the intended use position, in front of the face or at the body in the PTT mode or alongside of the head in the phone mode, then ensure the antenna and the radio are kept 2.5 cm (one inch) from the body when transmitting. Keeping the radio at a proper distance is important because RF exposures decrease with increasing distance from the antenna.

Protect Your Hearing

1. Use the lowest volume necessary to do your job.
2. Turn up the volume only if you are in noisy surroundings.
3. Turn down the volume before adding headset or earpiece.
4. Limit the amount of time you use headsets or earpieces at high volume.
5. When using the radio without a headset or earpiece, do not place the radio's speaker directly against your ear.

Note:
Exposure to loud noises from any source for extended periods of time may temporarily or permanently affect your hearing. The louder the radio's volume, the less time is required before your hearing could be affected.
Hearing damage from loud noise is sometimes undetectable at first and can have a cumulative effect.
