4.4.7.2 Select Beacon Mode
Pressing the [MODE] key and then the [BCN] key activates or de-
activates the BEACON MODE. When the BEACON MODE is selected,
the transceiver transmits a sweeping emergency audio signal on the
selected channel frequency and in the selected modulation mode (AM or
FM). The display alternately switches between the word "BEACON"
and the selected channel information. No other operating functions are
available when the BEACON is active.
When the beacon mode is de-activated (by toggling the mode off or by
turning the power OFF and then ON), the transceiver goes back into
normal mode using the channel that was in use immediately prior to
entering the BEACON MODE.
4.4.7.3 Internal Voltage Measurements
Press the [MODE] key and then the [METER] key to activate the
METER MODE. Press the [R/T] key to
display the voltages of the
internal power supplies and of the batteries. The first time [R/T] is
pressed the voltage of the +5VDC supply -
consecutive press of [R/T] brings up the next supply; PS2: +12VDC,
PS3: -5VDC, PS4: -12VDC, PS5: +24VDC (external power batteries),
PS6: +70VDC and AGC.
NOTE
The voltages displayed on the front panel are relative voltages. If a
voltage/s appears to be too low or too high, measure the suspected
voltage using a lab type voltmeter. The AGC level displayed is a relative
expression of voltage only. The AGC level is expressed as a digital value
from 000 to 255.
