Baofeng UV-5R23Chapter 6. Dual WatchIn 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 radioand flip-flop between two frequencies at a fixed interval (known as Dual Watch), or youcan equip a radio with two receivers (known as Dual Receive or Dual VFO). The formermethod is cheaper to implement and far more common than the latter.The Baofeng UV-5R features Dual Watch functionality (single receiver) with the abilityto lock the transmit frequency to one of the two channels it monitors.Certain functions are not available while in dual watch mode:• You cannot use the reverse function.• You cannot use the key to switch between high and low transmit power inchannel mode.• You cannot save duplex channels.Procedure 6.1. Enabling or disabling Dual Watch mode1. Press the key to enter the menu.2. Enter on the numeric keypad to get to Dual Watch.3. Press to select.4. Use the and keys to enable or disable.5. Press the key to confirm.6. Press the key to exit the menu.Due to the way the Baofeng UV-5R is constructed, whenever one of the A and B channelsgoes active, it will default to transmit on that channel. This behaviour can be highlyinconvenient, especially if you're listening to a frequency you're not allowed to transmiton. Luckily there is a menu option available to lock the transmitter to one of the A andB channels.Procedure 6.2. Locking the Dual Watch transmit channel1. Press the key to enter the menu.2. Enter on the numeric keypad to get to TDR-AB.3. Press to select.4. Use the and keys to select A (upper) or B (lower) displays.
