VII. Function operation
i Basic operation
1. Startup and shutdown
In shutdown state, after turning on the two-way radio by pressing key, the two-way radio rings, all icons are displayed on the screen instantaneously. Current channel (1-22 channels in total) and 0-38 interference cancellation mute codes are displayed.
In startup state, turn off the two-way radio by pressing key at the top.
Tips: Etiquette or the use of wireless two-way radio
The 1-22 channels resources of your wireless two-way radio are shared with others and used in turn. Other groups may be using certain channels. To avoid interrupting the call of others and in order to have a better call yourself, please don't occupy the channel which is being used by others.
You may try to change channel to avoid blocking, or use the monitoring (MONI) key to check the activity condition of the channel. If you hear noise after pressing the monitoring key, representing that the channel is idle and can be used.
2. 8-level digital volume adjustment
In standby mode, by pressing [p] key, this two-way radio enters volume adjustment mode, and the screen shows current volume level; the volume can be adjusted to the maximum value by pressing [p] key continuously; by pressing [q] key, this two-way radio enters volume adjustment mode; the volume can be adjusted to the minimum value by pressing [q] key continuously.
Tips: Volume Level 1 is the minimum volume and Volume Level 8 is the maximum volume.
3. Talkback (transmitting and receiving)
When making calls with each other with wireless two-way radio, two-way radios of the same group must be set as the same channel (1-22) and interference cancellation mute code (0-38). When making calls to other groups without interference cancellation mute code, please set the interference cancellation mute code as OF.
l In order to improve call clarity, keep the microphone about 5~7.5cm away from mouth.
l By pressing and holding the call [PTT] key, the two-way radio gets into transmitting state, and the transmitting light (red) is on. Speak to the microphone with a normal tone, when doing this, the microphone shall be kept about 5~7.5cm away from mouth.
l End the call by releasing call [PTT] key. Now the two-way radio gets into receiving state.
Tips: about communication range
In order to optimal performance and communication range designed for the two-way radio, it is suggested that the distance shall not be too short when using the two-way radio. It must be over 1.5m. Communication range is shown below for reference:
l Optimal communication range, flat and open area;
l Medium communication range, when blocked by buildings or trees;
l Minimum communication range, when blocked by dense trees or mountains, or when in buildings or vehicles.
4. Key locking function
MENU key, SCROLL keys (pq), CALL key, SCAN key, FM key and SOS key can be locked via key locking function to avoid unintentional change of various settings of the two-way radio. Once the function is activated, you can only use key (startup/shutdown) and PTT transmitting function.
