Mount the encoder modulator in vertical position with the connectors

located on the top side.
When replacement parts are required, be sure the service technician has

used replacement parts speci ed by the manufacturer or have the same
characteristics as the original part. Unauthorized substitutes may result in
 re, electric shock or other hazards.

Safety check- Upon completion of any service or repairs to this device, ask

the service technician to perform safety checks to determine that the device

is in proper condition.

Power precautions

The encoder modulator is powered with a voltage of 12V DC. The power

supply voltage must not exceed the recommended voltage, which otherwise
may cause irreparable damage to the device and the invalidation of the
warranty. Therefore:

- Do not replace power supply with a voltage greater than 12V DC.

- Do not connect the device to the power if the power cord is damaged.
