OPEN SCANNING
To commence open scanning, select the OPEN SCAN mode by selecting the 05/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 isfound, 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’t wish to listen to a busy channel, you can SKIP over it by pressing either the
MEM switch (16) on the radio, or the MEMi/SKIP switch (2) on the microphone. The receiv­
er will immediately resume scanning.
To manually hold a chanrtel indefinitely (temporarily inhibiting the scan function), momen­
tarily press the PTT switch (1), and the radio wit! cease scanning and will hold on the
channel which was being scanned. The HELD channel can now be used for norma! 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 chan nel, i ,e, all 40 channels can be
scanned in 2.8 seconds.
