4.4 Low battery warning
4.4.1 The normal battery warning:
About 1 hour before the battery power is out, the main LED light of KL4MS /KL5MS /KL8MS
/KL12MS flashes softly (one time flashing for every five seconds) to remind the user that the
power is nearly used up and needs to be recharged. If you don’t want the flashing to affect the
normal lighting, you can press the switch more than 2 seconds. The main light source will flash
two times, and the flashing is away. Then the cap lamp restores to normal working.
4.4.2 The least battery warning：
When the battery is only able to keep the cap lamp on for 10 minutes, its main light source will
flash with the strong and soft light quickly (one time flashing for every two seconds). This
information is to remind you that the battery is nearly used up and it needs recharging or
exchanging to the auxiliary light source.
