Transceive short messages with a hand (some translations may not be allowed, please enlighten!)
This feature allows you to send a short message to those receivers that have DTMF (dual-tone multi-frequency) functions, and the information content can include numbers 0-9, letters A-Z, and spaces.
Each information is transmitted or the receiving length cannot exceed 6 characters.
Note: This feature is only applied to a hand with a DTSS / PAGING function (DTSS & Message Paging System) is displayed below the native LCD.
1, information transmission mode
Two modes
A. Input directly in the DTMF panel, you must press # to confirm at the beginning and end, and the symbols corresponding to each letter are observed.
b, store information in memory, then send
2, use information memory
The transceiver can store 10 information
Memory stored procedure:
a, press the m key, then press the Message button to enter the information setting status
b, use the DTMF key to enter the information, the character corresponds to the table.
c, if input is incorrect, press VFO button, repeat step 2

[Additional function]
Audio warning system
In the audio warning state, when someone is in progress on this frequency, it will send a warning to remind you.
If you set a audio alert, you can't hear it. If the CTCSS is also open, the role of synthesis is similar to a private paging system.
The automatic shutdown (APO) function is blocked during the audio warning work.
Open the audio warning system:
1) Adjust the static noise knob (SQL) to the start. 2) Select a suitable tone, if you plan to use the CTCSS function, check if the CT indicator lights up.
3) Press the F button, then press the 0 key, the indicator light T.ALT lights up.
4) When this frequency is received, it is approximately every 5 seconds, and the indicator light T.alt and Busy will lit and accompany the beep.
5) While receiving the signal, the current time will also be displayed, each time you receive a new signal, this time is followed.
6) Press the PTT key to close the audio warning.
7) Press the F button, then press the 0 button to completely close the warning function.
Note: In order to make the audio warning function can work well in the case of CTCSS, the alarm must last for about 1 second to the received signal. This feature can also be used with the DTSS or paging (PAGING) function, at this time, the alert will occur only when the matching encoding is received.
Select the tone of the alert
Pressing the TONE button (European and British version of the machine to turn on the power switch while pressing the LAMP button), the alarm tone will become a tone similar to the telephone ringtone, repeating this step switching.
2. Received
If you want to be properly recedmed in the case of odor noise (SQL), DTSS, CTCSS or PAGING, you can press the MONI button. After press, the above features do not work.
