Transmission
To communicate, all radios in your group must be set to the same channel. Briefly press the Side key 1 to enable the Monitor
feature in order to make sure that the frequency is not busy, and then press the PTT button. Release the PTT key to receive.
Only one user at a time can talk during radio communications. Therefore, it is important not to transmit when you are
receiving a communication and use the transmission mode sparingly to allow other users to talk. Transmission consumes a
significant amount of energy and should therefore be used sparingly to prolong the battery life. If you are unable to contact a
station that you have no problems in receiving, the station may be using CTCSS tones or DCS codes.
Monitor
The Monitor feature is for excluding (opening) the Squelch, in order to listen to signals that are too weak to keep the Squelch
permanently opened. Hold down the Side key 1 to enable such function.
Scan
This function can be activated only by means of the optional programming software. To enable the Scan function, all 22
channels must be programmed. If you turn on the radio on channel 16, the scanning will automatically start. Whenever any
signal is detected, the scanning will stop on a busy channel. If the PTT is pressed, you will transmit on the latest busy channel.
Channel 16 is the priority channel; therefore if you don't pick up any signal when you press PTT, the radio will transmit on
channel 16.
Squelch
The Squelch function suppresses noises on free channels and allows receiving even weak signals. H-888S has 10 different
Squelch levels that can be set by programming software: 0 means that the Squelch is turned off; from level 1 to level 9 you
