3.3 Installing the chain counter

The chain counter must be positioned so that the
display will be easy to read. It should not be exposed
to direct sunlight. Secure the instrument in place
with the cradle provided, tightening the two
screws using a cross screwdriver.
For instructions on making electrical connections, see Chapter 7- WIRING DIAGRAM. The wires must have a minimum cross section
size of 1.5 mm². Install a 5 A (ampere) fast safety fuse on the positive (+) wire of the battery. Do not use the voltage generated by the
engine battery set to provide power.
The instrument complies with EMC standards and must be positioned at a distance of:
- 30 cm (~1 Ft) from the compass;
- 2 metres (~6.5 Ft) from radio transmitter equipment;
- Transmission frequency 433MHz
