2.3 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.
