2-3.3.2 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 will go back into normal
mode using the channel that was in use immediately prior to entering the
BEACON MODE.
2-3.3.3 Internal Voltage Measurements
With the transceiver set-up in the meter-mode per Paragraph 2-3.1.5.,
pressing the [R/T] key will 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 - PS1 is displayed. Each 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 not a
voltage. The AGC level is expressed as a digital value from 000 to 255.
2-3.3.4 Release from Remote Control
Pressing the [MODE] key and then the [R/T] key returns the transceiver to
local control from remote control. This sequence is called Release Remote
Key Sequence (RRKS). This key sequence has no effect if the transceiver is
not in the remote control mode. There is no on-screen indication that the
transceiver is back in local mode.
2-4. ECS-8 8.33 KHZ OPTION
This is the 8.33 kHz tuning increment / channel spacing option. The features of this option are
only available if this option has been installed. If your transceiver has this option installed, refer to
Section 5 for detailed information and operating procedures.
