Exposure awareness can be facilitated by the use of a product label directing users to specific user awareness information. Your Motorola two-way radio has a RF exposure product label. Also, your Motorola user manual, or separate safety booklet includes information and operating instructions required to control your RF exposure and to satisfy compliance requirements. -

Page 10: Operational Warnings
Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a portable radio is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of the vehicle. -
Page 11: Operational Cautions
Operational Cautions Antennas Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact with your skin, a minor burn can result. Batteries All batteries can cause property damage and/or bodily injury, such as burns, if a conductive material such as jewelry, keys, or beaded chains touches exposed terminals. -

A repair constitutes something done internally to the unit that would bring it back to its original condition. Items not considered as repairs are those in which an action is performed on a unit which does not require the outer casing of the unit to be opened in a manner that exposes the internal electrical circuits of the unit. -

Motorola offers long term support for its products. This support includes full exchange and/or repair of the product during the warranty period, and service/ repair or spare parts support out of warranty. Any "return for exchange" or "return for repair" by an authorized Motorola Dealer must be accompanied by a Warranty Claim Form. -

Technical Services (MTS). If no part number is assigned, the part is not normally available from Motorola. If the part number is appended with an asterisk, the part is serviceable by Motorola Depot only. If a parts list is not included, this generally means that no user-serviceable parts are available for that kit or assembly. -
Page 17: Radio Model Information
Radio Model Information Radio Model Information The model number and serial number are located on a label attached to the back of your radio. You can determine the RF output power, frequency band, protocols, and physical packages. The example below shows one portable radio model number and its specific characteristics. -

Page 19: Section 2 Theory Of Operation
General Description The radio comprises of one main PCB. This main PCB contains the RF and digital circuits. The VHF/ UHF compliant handheld transceivers consists of a receiver, a transmitter, a phase-locked loop (PLL) frequency synthesizer, control circuits and power supply circuits. -
Page 20: First Mixer
Squelch U201 has a filter that filters noise and has an internal amplifier that amplifies the noise to make it a DC voltage in order to control the squelch system. So, if the noise level is under a threshold, the microprocessor (U101) in the radio detects the DC level and un-mutes the radio. -

Pass Filter, Antenna Switch and an Auto-Power Control. TX Power Stage The TX VCO output signal is channeled by the TX power stage via an attenuator. The attenuator is pie style resister attenuator, and is used for isolation between the VCO and power amplifiers. -
Page 22: Auto-Power Control
U401 is passed to Q404 and Q405 which then produce a constant power output to the antenna. If the current is changed due to a change of battery voltage or load, the APC controls gate voltage of Q403 and the collector voltage of Q401,402 to keep the TX power stable. -

(SW/VOL1) and is amplified to a sufficient level to drive a loud speaker by U601 Audio AMP. U601 has mute/un-mute function by the audio-mute control in CPU. If U601 pin 2 is low, the audio amplifier goes into active mode. If pin 2 is high, the IC goes into mute mode. -
Page 24: Rx Sub-Audible Decode Circuit
RX Sub-Audible Decode Circuit The filter U202 is a 260Hz 8 order LPF to pass CTCSS, DCS signals and to block any other signals. The signals that pass the LPF filter changes this sub-tone to logic signals in the Q208 pass comparator (U202-D) so that the microprocessor can decode the CTCSS and DCS correctly. -
