Light-For-Me TEC User Manual

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.

Power source

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.
Switching on/off
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.

Maintenance

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.
