Handleiding

To send DTMF codes, press the key(s) corresponding to the message you want to send while holding down the PTT key.

In general, there are two forms of selective calling in two-way radio systems: Group call, and Private call.

Group call, as the name suggest, is a one-to-many form of communication. Every radio in your working group is configured the same way and any radio will

make contact with every other radio in the group.

Private call, some times also known as paging, is a one-to-one form of communication.

Every radio is programmed with a unique ID code. And only by sending out a matching code can you get that radio to open up to your transmissions.

6.2.1 Call With Signaling

A call with signaling refers to a call make to a target ID on a channel with signaling. The signaling type is DTMF signaling, which needs to be preset signaling

code, and the call is realized by encoding and decoding.

CPS Programming Path >> Programming >> DTMF System >> Call Code, Call Name >> ANI ID.

Configure the signaling code, mute mode, and PTT-ID for the channel.

With the above settings, press and hold the [PTT] key to making a call with signaling in the channel that is adapted to the DTMF signaling code. When the

receiving terminal receives the matching signaling, it can decode without performing any operations.

Note: Setting the PTT-ID to OFF will disable the use of the DTMF signaling function for this channel.

6.3 Dual Watch

In certain situations, the ability to monitor two channels at once can be a valuable asset. This can be achieved in one of two ways. You can either have one

receiver in your radio and flip-flop between two frequencies at a fixed interval (known as Dual Watch), or you can equip a radio with two receivers (known as

Dual Receive or Dual VFO). The former method is cheaper to implement and far more common than the latter.

The radio features Dual Watch functionality (single receiver) with the ability to lock the transmit frequency to one of the two channels it monitors.

Enabling or disabling Dual Watch mode

(1) Press the key to enter the main menu.

(2) Enter 3 on the numeric keypad to get to Radio Settings.

(3) Press the key to confirm, enter 14 on the numeric keypad to get to 14 Dual Watch.

(4) Press the key to select.

(5) Use the  or  keys to enable or disable.

(6) Press the key to confirm.

(7) Press to return to the previous menu.

The dual watch function is turned on, and the icon 'D' is displayed on the top line of the screen.

·Repeat the above operation, select "OFF", the dual watch function is disabled, and the icon 'D' on the top line of the screen disappears.

Note: When the dual watch function is turned on, the icon 'D' is displayed on the screen, and the "Singal Mode" submenu is automatically shielded

in the radio setting menu.
