POWER SWITCH
To switch the transceiver on, press and hold the knob until the radio powers up. The display will
show TECHNISONIC and the software version installed followed by the model number along with
which RF modules are installed. The display will then show the normal display. To switch off the
transceiver at any time, press and hold the knob for 2 seconds until the display shows OFF then
release. If it is desired that the radio powers up with the radio master in the aircraft, a power
jumper may be installed (see installation instructions) such that the radio is always on. The
battery master must be used to turn the radio off with this jumper installed.
2.4
KNOBS
The knob is a rotary encoder, which turns endlessly, meaning its actual position is not important.
The knob also has a push button incorporated in it so you can press the knob as well as turn it.
The knob will start out as a volume control. Pressing the knob again will change its function to act
as the channel selector. Pressing the knob again causes the keypad function to change from
function keys to number keys. The knob in this mode acts as a volume control. Another knob
press will bring you to the recall mode. In the recall mode, typing in the channel number will bring
you quickly to that channel without scrolling through channels in between. Pressing the knob
again brings it back to the volume control mode. The current function of the knob is shown at the
bottom right of the display.
2.5
SOFT KEYS AND HOME
The transceiver has three soft keys, which assume the function shown on the menu above them
on the display. The functions displayed depend on how the module was programmed with the
customer programming software (CPS)™. These menu items can be different on a channel by
channel basis. Typical menu items may include:
ZONE - Pressing this function will prompt you for a new zone number which can be entered
directly (if the keypad is in numlock mode) or scrolled using the UP(5) and DN(8)
keys.
MUTE - Selecting this function will prompt you for an on or off entry using the soft keys to
mute the tones. Tones refer to the beeps heard when pressing buttons.
PWR - Selecting PWR will allow the power output of the radio to be set to high or low.
PROG - Selecting PROG brings you to user programmable features of the radio such as
telephone numbers or scan lists. The ability for the user to program phone numbers,
scan lists, etc can be enabled or disabled by the CPS™.
VIEW - The view function is used to view lists. Lists can include scan lists, phone numbers,
call lists and or paging.
FPP - Front Panel Programming mode allows you to program at the front panel without the
customer programming software. This option is available on VHF and UHF type II
modules and is always present on band 5 (analog VHF low band module).
At any time while in one of these functions, you can escape back to the normal mode by pressing
the HOME key. When programming the modules with the CPS™, it is suggested not to double up
functions. For example, programming a soft key to CHAN would be redundant since there is
already a channel function using the knobs. Using the CHAN soft key would also not update the
channel number on the display, causing some confusion.
