Quick Start Guide
Before first use, we recommend you put the Biotracker on charge. The battery is fully-
charged when the receiver is manufactured, but rechargeable batteries self-discharge
slowly over time and after any period of storage will not be at full capacity.
Description of receiver operation
The receiver has three modes: Frequency, Channel and Scan.
Frequency Mode: Frequency is set directly via the numeric keypad or arrow keys.
Channel Mode: Channels holding stored frequencies are selected via the numeric
keypad or arrow keys. There are 256 channels.
Scan Mode: The receiver steps in numerical sequence through all channels or
selected channels only.

does not change the gain level displayed on the LCD.
