Model C860 Important Information

Intended Use

The 3M Belt Pack Intercom System, Model C860, is designed to provide 2-way
radio-frequency audio communication in quick service drive-through restaurants
and convenience stores.

Misuse of the Model C860 could result in poor performance and/or undesired
operation.

FCC Information

This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, including interference
that may cause undesired operation.

Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

Introduction

System

Single-Lane Standard
Communication
System

Single-Lane Duplex
Communication
System

Dual-Lane Standard
Communication
System

The 3M Model C860 Belt 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 stan dard c ommunica tion 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 belt 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 belt packs and battery
chargers.

The dual-lane stan dard co mmunicat ion 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 belt packs are programmed to work
with one system or the other and are labeled accordingly (1 or 2).

Dual-Lane Duplex
Communication
System

Cross-Lane
Communication
System

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 belt 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 belt 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 headset 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.

System
Components

Base Station

Headset and Belt Pack

The number of system components and the procedures necessary to operate
them vary depending on the system configuration. However, three components
are common to all system configurations.

The base station is the interface between the customer and the belt pack worn by
the operator. See Figure 1.

Figure 1. Base Station

The belt pack is used by the operator to communicate with customers and with
other store personnel who are wearing belt packs.

The headset is connected by a communications cable to the battery-powered belt
pack. See Figure 2.

Battery Charger

2  3M 2003 January

The battery charger charges batteries in approximately 1.5 to 2 hours. The
charger is available in 3-slot and 6-slot versions. See Figure 3.

This indicator lights when the ON/OFF switch is in the ON position.

 Note

If for some reason the C860 headset system does not operate and the system
includes an optional wired backup system, turn off the C860 Base Station to
enable the backup system.

With the switch in the DAY position, the volume of the menu sign speaker is
increased for daytime operation. With the switch in the NIGHT position, the
volume of the menu sign speaker is decreased for nighttime operation. (Sound
travels further and more efficiently at night.)

These indicators light to show which of the 8 channels is selected.
This indicator blinks when the Noise Reduction Module is switched on.
This button turns the optional Noise Reduction Module on or off.

This indicator lights when headset Page communications occur.
This indicator lights when headset–to–menu sign “Talk” communications occur.
This indicator lights when a vehicle is detec ted at the menu sig n.
This access hole allows for adjusting the volume of the optional monitor

speaker.

Switch

Press the volume down control to decrease the volume.
When either volume control is pressed, the headset emits a short tone to indicate

the new volume level. There are 15 different volume levels from minimum to
maximum.

If the headset volume is at its maximum level, a low, continuous tone sounds
when the volume up control is pressed. A low, continuous tone also occurs
when the volume reaches minimum level and the volume down c control is
pressed.

Note that even when set to its lowest level, headset volume is not turned
completely off.

Press the volume up control to increase the volume in the headset earpiece.

Press the ON switch to turn on the belt pack.
Press the OFF switch to turn off the belt pack.
For duplex systems where hands free operation is desired, press the talk lock

switch once to talk and listen to the customer. This enables hands-free
operation.

For dual-lane systems, press and hold the T2 (Talk Lane 2) switch to talk to the
customer at the menu sign in lane 2. Release the switch to listen.

For single-lane systems, both switches operate identically.
