SmaRT x18 Handheld Battery Installation
The handheld remote operates between 1.6 to 3.2 VDC powered by four factory installed 1.5 V
“AA” cell batteries. Cervis, Inc. recommends having fresh spare batteries on hand at all times
that the system is in use.
Note: The battery cover is designed so that the four screws holding the battery cover in
place are
“captive” to the cover. Although not easily removed from the cover itself, be aware
that if the screws are over-loosened while opening the battery compartment, they can be
completely removed, increasing the risk of loss. All four screws must be installed to maintain
a tight seal.
1. Place the remote face down, and remove the four screws holding the battery
cover in place. Remove the battery cover.
2. Remove the discharged batteries and properly dispose according to local
regulations.
3. Plug each fresh battery into a terminal cradle observing proper polarity. The
interior of the cradle shows polarity markings for each terminal (Figure 3). Make
sure the batteries are firmly seated in the cradle.
4. Replace the battery cover. Secure the cover with the four screws. Make sure
they are tightened enough to compress the seal, but be careful not to over-
tighten.

Observe proper polarity when placing batteries into the cradle.
Improper battery placement can cause excessive heat, battery
explosion, injury to the operator, and damage to the remote.

Note: Cervis, Inc. recommends removing the batteries from the handheld remote when it is
going to be stored for any extended length of time.
