Servicing
Servicing should be performed in accordance with the standard cycle established for the aid.
Ensure that the lens and solar panels are clean. Wipe with a cloth dampened with mild soap and
water, if necessary.
Using either the tap-to-activate digital LED display feature or the information key on the IR
remote programmer, check the battery state-of-charge: Look for battery state-of-charge reading
XXX (bAtt – SoC – XXX) in the digital LED display that will sequence immediately after
lantern status information. Battery state-of-charge must be at least 60%; if less than 60%, the
lantern must be removed from service for charging and troubleshooting. Since the two M800
lanterns use different battery configurations and voltages (M850/60X = 6.3 volts, M860/200BC
= 8.4 volts), we rely primarily on battery state-of-charge to determine the health and status of the
battery. However, battery voltage information can be useful when troubleshooting a discrepant
lantern and reporting back to customer service technicians at Carmanah for assistance.
Cover the lantern with a shroud, jacket, box, blanket, etc., to simulate darkness. The lantern
should flash on rhythm after a few seconds. While covered, confirm that all five LEDs are
operating (check the LEDs by looking around the lantern just above the lantern’s focal plane;
DO NOT look directly into the lantern with your eye at the focal plane).
Uncover the lantern. It should stop flashing.
Battery Service Life
The expected battery life is highly dependent on temperature: The higher the temperature, the
shorter the expected battery life. Battery recharge intervals (i.e., replacement intervals) range
from four years in hot climates to ten years in cold climates. Field units should recharge
(replace) batteries at intervals shown in the table on the next page.
A battery replacement kit can be ordered directly from Carmanah (see SECTION 6 below). The
battery kits contain a Cyclon battery pack, harness, battery hold-down plate, head/base gasket
and washers (lantern base not included). Detailed battery replacement instructions are included
with each kit. If the lantern fails due to a battery problem within the first year after purchase,
contact Carmanah’s customer service department at 1-877-722-8877 for an RMA number before
shipping the lantern back to them for repair or replacement.
