Leaving User calibration
Hold down the depth and speed keys for 2 seconds, to save your
settings, exit User calibration and resume normal operation.
4.3 Intermediate calibration
Intermediate calibration enables you to:
• Check the instrument software version.
• Check the instrument status - either YES (master)) or NO (repeater).
You can also change the depth status, as required. This feature is
particularly useful in preventing interference when using another
product (e.g. a fishfinder) that operates at 200 kHz.
• Carry out a calibration run over a measured distance to ensure
accurate speed readings.
To start Intermediate calibration, hold down the depth and speed
keys for approximately 4 seconds (see Intermediate calibration flow
chart).
To set the instrument status:
1. Press the depth key to select the Instrument status screen.
2. Press the trip and reset keys simultaneously to enter the depth
adjust mode, then press either trip or reset to set the required
status, i.e. either YES (for master operation) or NO (for repeater
operation).
Note: You must not allocate more than one master depth instrument in
any system.
3. Press the trip and reset keys simultaneously again, to leave the
adjust mode.
