When used as an Aisle Identifier or Roadway Marker, the unit is installed on a fixed structure

such as a rack using an interface mounting adapter. The location should be selected such that

the truck passing by will pass through the magnetic field from the Cab Silencer.

After installing the Cab Silencer, performance of the unit should be verified by operation and

test.

2.1.1 Inoperability Warning

The Cab Silencer may degrade the performance or blind the CAM when installed too close to

the CAM. A safe guideline is to keep the Cab Silencer at least 5ft away from the CAM. The

purpose of the CAM is to sense the magnetic field from a MFG on another lift truck. If the Cab

Silencer is closer than 5ft from the CAM, it may cause the sensing range of the CAM to be

degraded or blinded. Then a collision between trucks would be possible.

2.2 Charging

The Cab Silencer is directly powered and requires no charging.

2.3 Alerts

If a pedestrian with a PAD approaches a truck with a MFG system, their PAD could be silenced if

they stand too close to a truck with a Cab Silencer. The pedestrian is in danger of being hit by

the truck or a foot getting run over if their PAD is too close the Cab Silencer. The operator

needs turn OFF the truck while anyone is standing next to the truck.

2.4 Maintenance

The Cab Silencer should be regularly cleaned to reduce buildup of dust and dirt.

2.5 Selection of Operational Options

The Cab Silencer unit has three aforementioned operational

modes (Cab Silencing, Aisle Identifier, or Roadway Marker) that

can be selected using combination settings of the three-switch

unit “SW1” on the printed circuit board. Combinations of the

three switch settings allow eight different operational modes. A

multi-colored LED emits flashes every 15 seconds to denote which

mode is operating. The table below delineates switch

combinations for the eight modes and the corresponding LED

flashes.
