When in 2ndF setting, the side panel [FUNC] key need only be momentarily
pressed then released before pressing a second keypad option. A continually
flashing highlight cursor “F” indicates FUNCTION selection.
When in FUNC setting, the side panel [FUNC] key must be pressed and held
while a second keypad option is pressed. The flashing highlight cursor “F”
indicates FUNCTION selection.
The default setting of the [FUNC] key is “2ndF”.
5-10 [MONI] monitor (squelch defeat) key
This key is used to defeat the squelch (open it) to allow the
monitoring of very weak of fluttering signals.
5-11 [LAMP] lamp - LCD, keypad & side panel illumination
Attractive green rear illumination of the LCD (and keypad /
side panel) is switchable for use in locations of low level lighting.
Press the [LAMP] key to activate. The illumination will be active for about five
seconds then will automatically switch Off in order to conserve battery power
(use the lamp facility sparingly when powered from batteries). Should data be
keyed in, the five second timer will count from the last key press... this
eliminates any requirement to rush data input.
The five second illumination may be cancelled by pressing [LAMP] a second
time.
It is possible to switch the illumination On permanently for mobile operation
etc. The input regulator is deliberately overrated to allow for permanent
illumination. To activate permanent illumination press [FUNC] [LAMP]. The
illumination may still be switched Off by pressing [LAMP] which returns the
facility to timer operation.
The lamp is driven by an internal voltage inverter circuit so that the level of
lighting should not drop as battery voltage changes due to exhaustion (should
not dim). Of course the lamp illumination will cease to function when the
batteries are fully exhausted requiring recharging.
5-12 [K.LOCK] Keypad lock
The keypad and [DIAL] may be electronically locked during
use to prevent accidental change of frequency, mode etc.
This is useful when one particular frequency is being monitored
(such as an airshow) and the receiver is in a pocket.
To activate keylock press [K.LOCK]. The legend “KLCK” appears in the upper
left corner of the LCD to confirm keylock operation.
To deactivated keylock for normal operation press [FUNC] [K.LOCK].
