1.2 Unpacking and Inspection
Before unpacking the FD650/R and FD500/T or FD600/T, examine the
shipping carton for any sign of damage. Unpack and inspect the FD650/R
and FD500/T or FD600/T for any damage. If there is any damage then
consult your distributor immediately.
1.3 Battery Installation
Refer to Section 4.1 for battery installation instructions for the FD650/R.

3.1 Precautions
Warning Before use check the FD650/R and FD500/T or FD600/T for
cracks or any other damage, and make sure the units are free from dust,
grease and moisture.
Warning Hold the FD650/R by the bottom of the unit. Do not allow your
fingers to go beyond the LED indicators.
Warning Do not use if the battery cover is not fitted.
Warning Always perform a pre-check on the FD650/R and FD500/T or
FD600/T (see sections 3.3.1 and 3.4.1) before use.

Caution Where users have a Martindale kit that includes an E-Ze Check
Xtra or an E-Ze Test, do not have these or similar types of unit plugged in
when fuse finding.
Caution Avoid severe mechanical shock or vibration and extreme
temperature.
Caution Remove the batteries from the FD650/R when not in use for an
extended period to avoid corrosion from leaking batteries.
3.2 Description of Functions and Indicators
Auto Power Down:- The power down is activated after approximately 5
minutes without a valid signal. The power down mode can only be reset by
switching the unit OFF and then on again. In power down mode the typical
current drawn is 20μA.
The power down function can be deactivated by holding down the press
button when switching the unit on.
Buzzer:- An internal buzzer is used to inform the user when a signal has
been detected. In the fuse finder function the buzzer will continue to sound
even if the LED's are not illuminated, provided that a signal is present.
Function Selection:- The required function is selected by sliding the three-
position slide switch from OFF to FIND (Fuse Finder) or VAC (Voltage
indicator).
1.1. LED's:- There are two status LED's on the LHS of the unit. The top
one is green and shows battery status. Continuous illumination means that
the battery level is acceptable. Flashing means that the battery should be
replaced.
1.2. The red LED is only used for the FIND function and indicates that the
unit is in automatic sensitivity mode.
