g) Replace and screw down the battery strap.
h) Carefully drop the shell over the face panel and make
sure that the handle on the shell is right side up. Hold
the face panel in with your fingers, flip over the instru-
ment, and replace the four phillips-head screws.
2. Mechanical Care.
a) Although the Model 902 Locator has been designed to
be rugged and can withstand a reasonable amount of
shock, it should be handled with care. Heavy shock
can cause minor changes in the radio-frequency tun-
ing, which is undesirable although it will not render the
instrument useless. In general, care for the Model 902
as you might care for a portable AM/FM radio.
b) We do not recommend the addition of large metallic
objects to the shells or faces of the instrument. Both
the transmitter and receiver are tuned at the factory to
compensate for the batteries, circuit boards and other
metal in the instruments. Adding metal will detune the
instrument and should not be done unless a trained
technician is present to retune the instrument.
3. Troubleshooting.
If problems arise when attempting to operate the Model
902, the operator may perform some simple troubleshoot-
ing with little technical knowledge.
a) If the BATT light does not glow when the receiver or
transmitter is activated, it may simply mean that the
batteries need to be replaced. In this case, you may
verify that the transmitter has been activated by press-
ing the OUTPUT LEVEL button. If the HI light comes on,
