the one designed for this unit. Doing so could result in damage to
the unit.
This device is equipped with a four-level charge indicator (CI).
When DL4 is turned on and fully charged, all four LEDs light up.
When less than 75% of battery life remains, three LEDs are illu-
minated. If more than half the battery is drained, two LEDs are on,
while a single LED indicates that less than 25% of battery capacity
remains.
To charge your DL4, insert the Micro USB plug (MUSB) of the sup-
plied cable into the charging port (CP) and the larger USB plug
(USB) into any USB port. When fully charged, the device will allow
approximately 2 hours of continuous operation, or enough power
for imaging approximately 240 lesions at 30 seconds per examina-
tion.
After hundreds of charges, the battery's capacity will be reduced to
the point where it may be more convenient to replace the battery.
Replacement batteries are only available from 3Gen or an autho-
rized 3Gen dealer. To remove the battery (BT), remove the battery
cap (BC) by unscrewing the set screw (SSC) using the wrench
supplied with each DL4 replacement battery. Disconnect the small
white battery plug (BP) and slide the battery (BT) out. Insert a new
battery and reconnect the battery plug. Replace the battery cap
(BC) and secure it with the set screw (SSC).
