P370/P470 Keyless RF Scanners Product Reference Guide

Phaser-to-Phaser Co-Existence

Up to three P470/370 scanners within listening range (100 feet) of each other can be
operated on the same channel with little or no interference, assuming average scanning
rates.
For higher than average scanning rates, P470/370 scanners within listening range (100
feet) of each other should be operated on different channels, set apart by at least one
channel (for example, 2, 4, 6, etc.). Cordless Phaser scanners support up to 82
communication channels. Not all channels are available in all countries. Refer to
B, Radio Channels for more information.
Increase the number of RF Retries
If the scanner's transmission is not received by the cradle or the base's acknowledgment
response is not received by the scanner (see Communication Errors on page 2-2), the
scanner retransmits the lost or corrupted data. The scanner attempts 4 RF Retries (default)
but can be programmed to attempt up to 8.
Depending on your particular RF environment, additional retries may cause your scanner
transaction time to increase in the presence of heavy Spectrum24 traffic.

Charging the Battery

Before its first use, the scanner's battery must be charged. It can be charged:
• using the cradle
• using the UBC 2000.
Note: When the battery's charge is almost depleted, the scanner emits 4
Hi tone beeps, when the trigger is pulled, indicating that it must be
recharged.
