LIGHT FOR ME
backup user’s manual
TEC / 3XPG / 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.
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 new ones as they may be prone to flooding of the backup.
The orings 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 or grain from the orings before
twisting the body to the head.
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 (head twisted to the body) and dry it. Check the sealing
orings and grease them if necessary. Store the backup with the batteries taken out. Store the batteries according to their
manufacturer’s advice.
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.
Maintenance
1/3
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 after the light went off, you may flood
the backup.
Backup light is designed to be used underwater only. It is allowed to switch the
light on on the surface 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 yours or anyone else’s eyes.
Switching on/off
Light-for-me backup torch is powered by 3 x C-size
/rechargeable/ batteries. It is recommended to use
batteries of high quality and from a reliable source. Before
inserting the batteries into the backup’s body, check their
condition - do not use damaged or broken batteries. The
batteries 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 photo). Placing the
battery the other way may cause a complete and
irreversible damage to the light diode. Do not force the
batteries into the backup body, they should go in / out
easily. Always use the same brand of batteries, do not mix
old with new and empty with fully charged ones. If
powering the backup with the rechargeable batteries,
charge them according to the specification given by the
manufacturer with the appropriate and approved charger.

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
batteries, the inside should be rinsed with fresh lukewarm water and the
torch 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
batteries’ manufacturer for advice regarding the flood. For safety reason do
not use the batteries 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 set of batteries. If in doubt,
contact the light-for-me manufacturer.
The light flashes from time to
time, even with fully charged
batteries.
Check the batteries - if using rechargeable batteries, charge them if
necessary; damaged or suspiciously looking batteries should be replaced
with new ones. Check the backup with a different set of batteries. 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 batteries’ manufacturer for advice. Clean the ‘touch surfaces’
described above. Check the backup with a different set of batteries.
If necessary, contact the light-for-me manufacturer.
