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 par- ticularly useful in preventing interference when using another prod- uct (e.g. a fishfinder) that operates at 200 kHz.
•Carry out a calibration run over a measured distance to ensure accu- rate 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.
