6.2 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 [4] on the numeric keypad to get to Radio Settings. (3) Press the key to confirm, enter 16 on the numeric keypad to get to 16 Dual Watch. (4) Press the key to select. (5) Use the or keys to OFF or ON. (6) Press the key to confirm. (7) Press to return to the previous menu.

6.3 Manual Programming (Channels Memory)

Memory channels are an easy way to store commonly used frequencies so that they can easily be retrieved at a later date.

The radio has 10 zones, with a maximum of 100 channels stored in each zone. Each channel can store: Receive and transmit frequencies, transmit power, group signaling information, bandwidth, ANI/ PTT-ID settings and a six character alphanumeric identifier or channel name 1 .

Frequency Mode vs. Channel Mode
