Acquisition Tone
A 1962.9 Hz tone sent at full deviation, for 50 milliseconds,
from the repeater is used as acknowledgment, from the repeater,
that a busy tone was sent and signals the mobile that signalling
tones can now be sent.
Collect Tone
A Tone chosen from 34 standardized frequencies, ranging
from 508.6 Hz to 2792.4 Hz, is used as the first tone in the group
tone sequence. The collect tone is used to gather all mobiles
with the same collect tone for decoding a call. The duration of
the tone varies as a function of the number of channels which
are programmed into the mobile and/or repeater.
In a two tone call, the mobile sends the collected tone for a
programmable duration. In the four-tone call, the mobile al-
ways sends a 90-millisecond collect tone, which the repeater
regenerates, and sends for the correct duration.
Group/Individual Tones
Group/Individual Tones chosen from the 34 standard fre-
quencies, follow the collect tone. In a two-tone call, the second
tone is sent for 450 milliseconds. In a four tone call, the second,
third, and fourth tones are sent for 90 milliseconds, from the
mobile, and 180 milliseconds from the repeater.
RADIO OPERATION
Refer to Operator's Manual LBI-38694 provided with each
radio for complete operating instructions.
VISUAL INDICATORS

ALPHANUMERIC STATUS INDICATORS
Busy
When "BUSY" is displayed, an attempt to place a call has
been attempted but the selected GE-MARC system does not
have any available channels. If the "Call Retry" option has
been enabled during radio initialization by the system operator,
the radio will retry at 5 second intervals, up to 15 times unless
the END key is pressed or a channel is acquired, or an out-of-
range condition occurs.
Retrying
When "RETRYING" is displayed, the radio is attempting
to establish a channel.
Wait
"WAIT" is displayed when the radio is acquiring a channel
after call origination has begun.
STATUS INDICATORS
No Service
The NO SVC status indicator is displayed when an at-
tempted call cannot be completed because the unit is out of the
service area of the selected GE-MARC system.
Roam
The ROAM status indicator is displayed when the mobile
is on channel in the conversation mode.
Function
The FCN status indicator is displayed when the function
key has been pressed so that extended features can be accessed.
In Use
The IN USE status indicator is displayed when the radio is
transmitting in either simplex or duplex modes of operation.
