SWITCH, CONTROLS & CONNECTORS
Selection Switch A five position switch is used to control the
operation mode of the PULSE 8X.
Pos. 1) OFF - All power is disconnected from the
electronics. Batteries are charged in this posi-
tion.
Pos. 2) BATTERY CHECK/LED CHECK -In the bat-
tery check position the meter becomes a volt
meter showing battery voltage from 0-10 volts
(full scale). The detector will work with a
battery reading of 8 to 10 volts. Leak detec-
tion circuitry is also tested (red LED will light)
to ensure it is working.
Pos. 3,4,5) LO/MED/HI - Three different sensitivity set-
tings. Normal operation is in HI position with
LO/MED used to pinpoint targets that give a
very strong reading in the HI position.
Zero Adjust A control knob that adjusts the position of
the needle on the meter scale. With no metal
near the coil, the zero adjust knob is turned
clockwise until the audio just starts to sound
(about .2 on meter), and then the knob is turned
back slightly.
“Ear” Connector Provides the audio output to underwater or
land earphones. An audio signal will be heard
with a meter reading of .2 and above. The
frequency (tone) of the signal shifts with a
change in the meter. The earphone can be
connected to the detector in or out of water.
The single underwater earphone is used by
sliding it under the mask strap or into the
hood, on or near the ear. An optional dual
underwater headset is also available.

The stereo land headset should be kept out of
water. However, the connector is waterproof
and can be submerged with the detector when
wading in the water. The volume of the land
headset can be adjusted by a control knob on
the outside of each earmuff.
An optional “dual underwater headset”, a ste-
reo headset for underwater use, is also avail-
able.
Battery Charger The battery charger connector is located on
the back of the housing. The Selection Switch
must be in the OFF position for charging to
take place. It is not necessary to cover this
connector when diving.
Leak LED Illuminates if water has leaked into the elec-
tronics housing. When the Selection Switch
is in the Leak LED Position, the LED is forced
on for test. Actual sensing for leak occurs in
the Low, Medium, and High settings.
NOTE: If the battery voltage drops to 8 volts
or less (.8 on meter) the Leak LED will light,
giving a false leak indication.
Charge LED Illuminates when batteries are being charged.
Full charge will occur in 12 to 14 hours. The
light may go out when batteries are fully
charged.
