4TEC RCA head
Please read the following manual carefully before the first use and keep it for future reference.
Scuba diving is treated as an extreme sport and requires proper training and certification. Using scuba equipment, 3XML
Alexandra head included, by an untrained and inexperienced person without proper certification may cause health
damage and even risk of death.
Light-for-me 4TEC RCA head:
- 4 x XPE diodes
- up to 1200 lumens
- light angle: 6 degrees
- 18 W
- Piezo switch
- two modes of light: 30% and 100%

- detachable cable

SideMount (custom made): up to 123cm
Before the dive
Check the head’s visual condition - see if the front glass is not chipped or broken. Check the cable - if it is cut
or damaged. Check the cable’s RCA plug - it should be clean and dry, remove any dust or sand with a clean
tissue (see photo below).
Put the head’s RCA plug into the ACCUs cable entry, press it slightly and turn
the rotating cap tightly (see photos below).
Check if the head is working by pressing the switch - make sure the torch is
not switched on for more than 2-5 seconds on the surface. Switching the light
on on the surface and using it for longer time may cause overheating of the
LEDs and lead to irreversible damage (melt the optics and deform the front
glass) and cause flooding.
Do not direct the light into yours or anyone else’s eyes.
Operating the head - to switch between the modes press firmly the Piezo
switch: first press - 30%, second press 100%, third press - off.
Attach the 4TEC head securely to your dive harness when not held in hand. Do not let the light head dangle
or be dragged on the bottom during the dive.
Do not disconnect the head from the accu when under water - this will cause flooding and irreversible
damage to the head and the inside parts.
