NOTE:
- For the detection diode (D401: HSM276SR), the withstanding static voltage is very low. So, pay special
attention to static electricity to protect the diode from electrostatic damage when servicing.
- When the detection antenna has been removed from the upper case for servicing, be sure to stick it
onto the upper case with adhesive tape along the guide, after the repair is completed.

OPERATIONS
Power switch
Switches this unit ON/OFF.
Heat indicator
This lights when the unit’s internal temperature
becomes high. Power automatically switches
OFF. Power automatically switches ON when
the internal temperature decreases.
Sensitivity level switch
This allows you to adjust the sensitivity over which
cellular signals can be received.
High sensitivity level
Low sensitivity level
Keep the switch in the ON position when
using this product. The power switch is
interlocked with that of the head unit, and
is automatically swithed on and off as the
head unit is operated.
