Apex ht-175 User Manual

Remove the battery compartment cover.

Load two AAA batteries into the battery 
compartment.

Make sure that the batteries have been inserted 
properly, matching to the symbols 
+, - marked in the battery compartment. Close 
the battery compartment cover.

When replacing batteries, replace both batteries. 
Do not mix new and used batteries  
together, otherwise, battery life will 
be much shorter than normal.

Remove the batteries if the unit will not be used 
for a prolonged period of time.

The remote control transmits a directional 
infrared beam. Be sure to aim the remote 
control directly at the infrared sensor of the 
unit during operation. 

If the sensor has been covered or there is a 
large object between the remote control and 
the sensor, the sensor will not respond. 

The sensor may not able to receive the 
remote signal when it is exposed to direct 
sunlight or a strong artificial light (fluorescent 
or strobe light). In this case, change the 
direction of the light or reposition the unit to 
avoid direct lighting.
