Protective Rubber Boots
A protective rubber boot is installed over each end of the GP-01. The
sensor end boot fits over the sensor cover end of the GP-01 and the
battery end boot fits over the battery cover end of the GP-01. If you have a
Ni-cad battery pack in your GP-01, you must remove the battery end boot
to insert the GP-01 in the charger.
Case
The Model GP-01’s sturdy, high-impact plastic case is blue in color. The
case is suitable for use in many environmental conditions, indoors and out.
The unit is dust proof and weather resistant.
The front of the case has an LCD (liquid crystal display) that shows various
readings, which are described under “LCD” in this section. To the left of the
LCD is an alarm light. Below the LCD are two black control buttons. The left
button is labeled “POWER/MODE” and the right button is labeled “AIR.”
On top of the case and to the left is the Model GP-01’s buzzer, which is
located inside the unit. To the right of the buzzer is the sensor. The sensor
is held in place by the sensor retainer (the top of the case for the Model
GP-01) and two screws. The sensor is protected from dirt and moisture by
a filter disk. This filter is secured by a membrane retainer and a single
screw. To the left of the sensor and below the buzzer, is a second alarm
light, which is also visible from the front of the case.
The battery compartment is located on the bottom of the case. Access to
the compartment is accomplished by turning the captive battery cover
screw counterclockwise and by removing the battery compartment door.
There are two threaded holes on the back of the case. These are used to
mount the optional alligator clip or belt clip. Toward the bottom of the back
are two battery charging contacts. These contacts are used when the
Model GP-01 is placed in its optional battery charging station whenever the
unit’s optional Ni-cad battery pack requires recharging.
The wrist strap connects to the back of the case on the left side, near the
top of the unit.
