OPEN SCANNING

To commence open scanning, select the OPEN SCAN mode by selecting the OS/GS Select switch (4) to the IN position. Then select the SCAN switch (3) to the IN position.

The SUNDOWNER UH-077 will commence scanning the programmed channels, and will indicate each channel on the CHANNEL indicator (12) as it is scanned.

When a busy channel is found, the radio will 'lock'onto it, and will remain there for as long as the signal is present, and for 3 seconds after the transmission ceases. This allows the SUNDOWNER UH-077 to hold the channel during short breaks in the conversation. Once the channel has remained clear for 3 seconds, the radio will resume scanning.

If you don'twish to listen to a busy channel, you can SKIP over it by pressing either the MEM switch (16) on the radio, or the MEMlSKIP switch (2) on the microphone. The receiv- er will immediately resume scanning.

To manually hold a channel indefinitely (temporarily inhibiting the scan function), momen- tarily press the PTT switch (1), and the radio will cease scanning and will hold on the channel which was being scanned. The HELD channel can now be used for normal trans- mission and reception.

To RESUME scanning - whether automatically 'locked'on a busy channel, or manually HELD - press the MEM switch (16) on the front panel, or the MEM/SKIP switch (2) on the microphone, once. The radio will begin scanning again.

NOTE: 1. During OPEN SCAN mode, the CHANNEL SELECTOR switch (20) is igno- red.

2.The scan rate in this mode is 70 msec per channel, Le. all 40 channels can be scanned in 2.8 seconds.
