5. MAINTENANCE
5.1 Battery replacement
Low battery indicator
This message warns the battery voltage is below the minimum recommended
and it needs to be replaced with a new battery.
If the battery voltage is low, but still allows for the operation of the instrument,
when turning it on the alphanumeric display will show a low battery condition for
2 seconds and resume operation as normal.
When turning the unit on, if the battery voltage is below the absolute minimum
operating voltage, it will show a low battery condition for 2 seconds, and turn off
automatically in order to prevent malfunction. If the unit is operating and the battery
falls below the minimum level, it will show a low battery condition for 8 seconds,
and turn off automatically.

5.2 Cleaning
Keep the instrument in its carrying case when not in use and do not subject it to dampness
or severe heat or cold. Do not use the instrument in the rain, if it should accidentally get
wet, dry it off with a clean paper towel before storing away.
Protect the unit from contact with any solvents. Never clean with a solvent or petroleum
based medium such as gasoline, as these chemicals may attack the plastic parts and
cause permanent damage. Never use an abrasive cleaner. Cleaning should be limited to
wiping with a clean damp paper towel and a small amount of soap if required. Dry the unit
thoroughly after any cleaning.
The unit is a sealed instrument and contains no user serviceable parts other than the bat-
tery, which can be replaced by opening the drawer on the back of the unit. Opening other
parts of the unit will void the warranty.
6. WARRANTY
With the exception of the battery, this instrument is warranted against defects of material or
workmanship which develop within a period of one (1) year following the date of purchase
by the original owner. Proof of date of purchase will be required when applying for repair
or replacement under warranty. For this reason, we strongly suggest that you keep your
sales receipt in a safe place.
In the event that a flaw develops, please return it to your dealer who will arrange for repair
or replacement. The manufacturer will either repair or replace the tool (at the manufacturer’s
option) free of charge providing the instrument is still under warranty. If the warranty has
expired, there will be a repair charge payable to your dealer when you pick up the unit.
When a unit has been repaired or replaced under warranty, the replacement unit will con-
tinue the warranty period of the original unit for six (6) months after the date of replace-
ment or until the original warranty expires, whichever is the longest period. This warranty
shall not apply to any defect, failure or damage caused by improper use or inadequate
maintenance or care.
The manufacturer shall not be obligated to provide service under this warranty or to repair
damage resulting from attempts by unauthorized persons to repair or service the instru-
ment, other than to replace the battery; or to repair damage resulting from improper use.
Specifically if there is evidence of an attempt to open the instrument the warranty is void.
Any implied warranties arising out of the sale of the instrument including but not limited to
implied warranties of merchantability and fitness for a particular purpose are limited in dura-
tion to the above one (1) year period, the manufacturer shall not be liable for loss of use of
the instrument or other incidental damages, expenses or economic loss. Some Jurisdictions
do not allow limitations on how long implied warranties last or the exclusion or limitation of
incidental or consequential damages, so the above may not apply to you.
