dashes are displayed in the „STBY” window.
2. Turn either frequency selection knob to change the channel number and the
channel’s corresponding frequency in the „STBY” window.
3. If there is no activity for ve seconds, the radio will exit the Channel Mode
and return to the Frequency Mode, with the channel frequency remaining in the
„STBY” window.
4. You can also return to the Frequency Mode by either:
a. Pressing the channel button before the ve-second delay, in which case the
radio recalls the „USE” and „STBY” frequencies prior to entering the Channel
Mode, or
b. Pressing the transfer button, so that the channel frequency becomes the active
frequency and the last „USE” frequency becomes the new „STBY” frequency.
NOTE: If the optional remote channel increment switch is installed, each acti-
vation of the switch will put the unit in the Channel Mode and advance the
channel number from the previous channel used.
NOTE: If the optional remote channel increment switch is installed, each activati-
on of the switch will put the unit in the Channel Mode and advance the channel
number from the previous channel used.
Direct Tune Mode
The Direct Tune Mode is entered by pressing and holding the transfer button for
longer than two seconds. The „STBY” frequency will disappear and the frequen-
cy in the active window can be changed with the frequency selection knobs.
Momentarily pushing the transfer button will return the unit to the Frequency
Mode (normal operation). The „STBY” frequency displayed prior to entering the
Direct Tune Mode will return unchanged.
