ROTALIGN components
Laser battery
The ROTALIGN laser is powered by a single 9 V battery (type
IEC 6LR61) which, depending on battery make and operating pat-
terns, provides a typical operating duration of 80 hours. Note,
Lithium batteries of this size can also be used, increasing operation
up to 150 hours.
As the battery becomes depleted, the color of the 'laser active'
indicator LED (see previous page) changes from red to yellow (or,
for older models, from red to green). When this occurs, the battery
should be replaced as follows:
The battery is replaced by removing both screws from the battery
compartment cover of the laser housing as shown above.
Used batteries should be disposed of in an environmentally-sound
manner!
Be aware that when NiCad rechargeable batteries are used as
replacements, their voltage tends to drop quite rapidly as they
become depleted. This may limit the effective warning time (see note
above), so a fully-charged spare should be held in reserve.
Under no circumstances may the four smaller housing screws be
removed, as that would result in misadjustment and would void all
warranty coverage.
