Housing of DX-2G: once in how long to replace buttons O-rings (if at all)?

[A_kaza]

Hello,

In the past I used Motormarine-IIEX (for 13 years) and for the last ~10 years of them I used to perform the annual maintenance myself,
replacing all the small O-rings of all the controls of the camera and the YS-60 strobe.
For the last 1.5 years I own the DX-2G and YS-110a strobe and I would like to know what are the periodic replacement
recommendation for the small O-rings of the housing buttons (the main O-ring I replace annualy)?

Is it once a year?
Is it once in few years?
Never?

TIA,
A_kaza.

Hi-
Service will depend upon your usage - over 50+ dives/year an annual service and pressure test on the housing is recommended. Replace the main body o-ring and strobe battery cap assembly o-ring as necessary with wear, but at least annually. Please contact your local distributor or dealer for service and parts information.
