LIGHT FOR ME
backup MINI user’s manual
MINI TEC, MINI 3XPG, MINI XML
Please read the following user’s manual carefully before the first use of the products and keep it for future
reference. Scuba diving is treated as an extreme sport and requires proper training and certification. Using scuba
equipment by an untrained and inexperienced person without proper certification may cause health damage and
even risk of death. Light-for-me backup lights are designed to be used underwater only.
Light-for-me backup MINI is powered by 1 x 18650 Li-Ion
rechargeable battery. It is recommended to use battery of
high quality and from a reliable source.
Before inserting the battery into the backup’s body, check
its condition - do not use damaged or broken batteries.
The battery should be put into the backup’s body with
the sign – (minus) to the head and with the sign +
(plus) to the inner part of the body (see the photo).
Placing the battery the other way may cause a complete
and irreversible damage to the light diode. Do not force
the battery into the body, it should go in / out easily.
Charge the battery according to the specification given by
its manufacturer with an appropriate and approved
charger. 18650 Li-Ion batteries require a dedicated
charger.
Power source
Light-for-me backup is switched on/off by twisting the head to the body. To
switch the light on, hold the body with one hand and twist the head in a clockwise
direction with the other. To switch the light off, hold the body with one hand and
twist the head in an anticlockwise direction with the other.
When switching the backup off under water, stop twisting the moment the light
goes off. If you continue to twist the head, you may flood the backup.
Do not switch the light on when not in water for more than 5 seconds. It is
allowed to switch the light on to test if it works properly, but for maximum of 5
seconds. Longer use of the light on the surface may cause the LED to get too
warm and get damaged as a result. Do not direct the light into your or anyone
else’s eyes.
Switching on/off
Before every dive check the condition of orings that seal the body of the backup torch. Torn, cut or damaged orings should
be replaced for a new ones as they may lead to flooding of the backup.
The oring sealing the body to the head should be lightly greased with technical petroleum jelly (pure vaseline) which makes
it easier to operate the light underwater and helps it stay watertight. Remove any dust, mud or sand from the orings before
twisting the body to the head.
From time to time clean the surface that touches the inside of backup head (marked in the drawing) and the silver ring
around the spring inside the backup head. These surfaces need to be clean and grease-free in order for the backup to work
properly.
While slowly twisting the body to the head make sure the sealing orings are correctly placed in their position and are not
twisted or sticking out. Orings should sit firmly in their grooves and should not be too loose as they may not work properly
underwater.
After each day of diving, rinse the backup in fresh water and dry it. Check the sealing orings and grease them if necessary.
Store the backup with its battery taken out.

3/3
Battery should not be longer
than its pocket. It should not go
beyond the marked edge of the
pocket. A longer battery may
cause improper working of the
backup torch.
Troubleshooting
Problem Solution
I have flooded my backup.
I can see some water inside the
head.
In case of flooding the torch: untwist the head from the body, remove the
battery and dry it, the inside should be rinsed with fresh lukewarm water and
backup should be left open for the time of at least 72 hours. The head should
be left to dry with the glass directed downwards while drying. The flooding of
the head may result in lowering the power of emitted light. Check the battery’s
manufacturer advice for flooding the battery. For safety reason do not use the
battery again. Contact the light-for-me manufacturer.
I charge the batteries full but
still get less burn time than
stated.
It is recommended to use high quality genuine batteries. Burn times given
with each backup torch are based on the data given by their manufacturers.
Burn time may differ +/-10% from the stated one depending on the ambient
conditions when diving and battery- / charger-related issues. If the burn time
is visibly shorter, try the backup with a different battery. If in doubt, contact
the light-for-me manufacturer.
The light flashes from time to
time, even with fully charged
batteries.
Check the battery - charge it if necessary; damaged or suspiciously looking
battery should be replaced with a new one. Check the backup with a different
battery. Clean the ‘touch surfaces’ described above. Should the issue
continue, contact the light-for-me manufacturer.
I have forgotten to take out the
batteries after my last dive and
the backup does not work now.
Check the battery’s manufacturer for advise. Clean the ‘touch surfaces’
described above. Check the backup with a different battery. If the issue
continues, contact the light-for-me manufacturer.
