Model C1025 System Descriptions
©3M 2006 1
The 3M Model C1025 Transceiver Pack Intercom System is a wireless
intercom system designed for high reliability, compactness, and ease of
service.
The system can be programmed to operate on any one of eight different
radio channels to provide high-quality audio performance and reduce the
possibility of interference between neighboring wireless systems.
The system can be configured in one of five ways depending on the number
of menu signs (lanes) at the facility and the type of communication desired.
The single-lane standard communication system provides standard
communication (talk or listen) for facilities that have one menu sign.
The system consists of one base station and one or more transceiver packs
and battery chargers.
The single-lane duplex communication system provides duplex
communication (simultaneous talk and listen) for facilities that have one
menu sign.
The system consists of one base station and one or more transceiver packs
and battery chargers.
The dual-lane standard communication system provides standard
communication (talk or listen) for facilities that have two menu signs.
The system consists of two independent systems - one dedicated to menu
sign 1 and the other dedicated to menu sign 2. The transceiver packs are
programmed to work with one system or the other and are labeled
accordingly (1 or 2).
The dual-lane duplex communication system provides duplex
communication (simultaneous talk and listen) for facilities that have two
menu signs.
The system consists of two independent systems - one dedicated to menu
sign 1 and the other dedicated to menu sign 2. The transceiver packs are
programmed to work with one system or the other and are labeled
accordingly (1 or 2).
The cross-lane communication system provides duplex communication
(simultaneous talk and listen) for facilities that have two menu signs.
The system consists of two duplex systems that are connected to a cross-
lane module. The transceiver packs are programmed for either lane 1 or
lane 2.
During off-peak hours, the cross-lane module can be turned ON to link the
two systems and enable one operator to simultaneously talk and listen to
customers at menu sign 1 or menu sign 2 or with other earset operators.
During peak hours, the cross-lane module can be turned OFF to separate the
systems and enable menu sign 1 operators to talk to customers at menu sign
1, and menu sign 2 operators to talk to customers at menu sign 2.

functions like a dual-lane duplex system. Some transceiver packs are
programmed to communicate with Lane 1 and others are programmed to
communicate with Lane 2.
Communication During Off-Peak Hours
During off-peak hours, the cross-lane module is turned on to enable a
single operator to communicate with customers in either lane (1or 2).
1. An alert tone sounds in the headset when the system detects a
customer (vehicle) at the menu sign:
• The alert tone for Lane 1 transceiver packs is a single beep that
repeats at 2-second intervals.
• The alert tone for Lane 2 transceiver packs is a double beep that
repeats at 2-second intervals.
2. When you hear the single beep alert tone, press and hold T1 and talk
to the customer at menu sign 1. Release T1 to listen.
When you hear the double beep alert tone, press and hold T2 to talk

When the battery voltage is too low, the headset sounds a short, low-
volume tone at seven-second intervals to alert the operator to install a
fully charged battery. The "battery voltage low tone" continues for two
minutes after which the transceiver pack turns off automatically to
prevent damage to the batteries.
9Note
When installing a battery, make sure it is fully charged. It is important to
remember that an unused C1025 battery loses five percent of its charge
per week. If a battery has not been used for several weeks, make sure to
charge prior to use.
To replace the battery:
1. Push the battery release to release the battery. See Figure 12.
2. Remove the discharged battery from the transceiver pack.
3. Insert a fully charged battery in the unit. Make sure the battery is
fully inserted (battery release clicks). See Figure 12.
9Note
The C1025 can operate on one battery or two. Using two batteries doubles the
operating time between charges, and increases operating range.
If two batteries are used, both must be recharged at the same time.
