1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section carefully

before use.

• Make sure to observe the instructions in this manual as

the conventions of safety symbols and messages

regarded as very important precautions are included.

• We also recommend you keep this instruction manual

handy for future reference.

When Installing the Unit

• Do not expose the unit to rain or an environment where it

may be splashed by water or other liquids, as doing so

may result in fire or electric shock.

• The equipment shall be fed from a power supply which is

in compliance with requirements of SELV circuit on the

EN60950 standard.

When Installing the Unit

• Do not mount the module in equipment other than those

designated. It is identical to the WTU-860 and WTU-870

wireless tuner modules in shape. However, since its pin

arrangement differs, it does not operate correctly when

mounted in the tuner (such as the WT-860 and WT-870)

other than those designated. This could also cause

failures to the tuner in which the unit is mounted.

Please follow the instructions in this manual to obtain the optimum results from this unit.

We also recommend that you keep this manual handy for future reference.
