• Receive Level Adjust: Used to adjust the receive level of the base station
two-way radio when there is no external volume control on the base station
radio.

Note: The receive level is set at the factory and should be adjusted only if the
remote radio does not have its own volume adjustment. The default is 12
o'clock, (1/2 rotation).

• Transmit Level Adjust: Use the TRANSMIT LEVEL ADJUST volume control
to set the level of the intercom's audio as heard at the remote station radio. The
factory default is 12 o'clock, (1/2 rotation).

• Transmit Delay: This rotary switch enables and adjusts the key up delay
available for each two-way radio. The available settings are shown in Table 1.

• Audio LED: This green LED illuminates when the system has sensed audio
from another channel and is supplying audio to this channel to be retransmitted.

• Key LED: This red LED illuminates when this channel is keying its associated
transmitter.

• Level LED: This bi-color red/green LED indicates audio levels received into
the system. Use this indicator to adjust the volume control on the two way radio
to match the system levels. The LED turns red when the signal is too high. Note
that proper audio levels cause the LED to light green when speaking, but flash
red about 10 percent of the time.

• Power LED: This green LED illuminates when the system is receiving AC
power and is turned on.

• Fault LED: This red LED illuminates when the system is receiving AC power
and is turned on, but it has detected a problem with one of its internal power
supplies. The TW-60 may still operate in this condition, but service is required
to correct this condition.
