5 POWER CONTROL SWITCHES - A group of five switches designed to
Switch/Indicators select five customer adjustable transmitter operating
output power levels.
In the AM-2.5E, switches 1 and 2 can be adjusted to
obtain output power levels from 250 to 1250 watts.
Switches 4 and 5 can be adjusted to obtain output
power levels from 750 to 2800 watts. Switch 3 is
designed to be customer assigned to control power in
the 250 to 1250 watt range or the 750 to 2800 watt
range.
In the AM-5E, switches 1 and 2 can be adjusted to
obtain output power levels from 500 to 2500 watts.
Switches 4 and 5 can be adjusted to obtain output
power levels from 1500 to 5600 watts. Switch 3 is
designed to be customer assigned to control power in
the 500 to 2500 watt range or the 1500 to 5600 watt
range.
INDICATORS - Illuminates to indicate an associated
power control switch has been selected.
6 OFF Switch/Indicator SWITCH - Deenergizes the transmitter RF output
power and configures the unit to off.
INDICATOR - Illuminates to indicate the
OFF
switch has been selected.
7 POWER Switch/ SWITCH - Instructs the system controller to raise
Indicator the transmitter output power. The switch is designed
with the ability to raise power from 10% to 15% of the
selected output power level.
INDICATOR - During manual operating conditions,
illuminates to indicate the POWER switch is
selected. During automatic raise conditions, the indi-
cator will illuminate to indicate the rate of automatic
power increase.
8 POWER Switch/ SWITCH - Instructs the system controller to lower
Indicator the transmitter output power. The switch is designed
with the ability to lower power from 10% to 15% of the
selected output power level.
INDICATOR - During manual operating conditions,
illuminates to indicate the POWER switch is
selected. During automatic lower conditions, the
indicator will illuminate to indicate the rate of auto-
matic power decrease.
