Introduction

GSM Mercury communication unit is the newest in OCEANREEF range of products.

Its frequencies are compatible with the other communication systems on the market. 
The high quality of the product  does not allow the user to ignore the problems connected with the 
correct use of the product and the rules for safe diving.

 

Use of SCUBA equipment by uncertified or untrained persons is dangerous and can result in 

serious injury or death.

NEVER wash any part of the communication unit with anything else than fresh water and 
the compartments opened and/or unscrewed.

DO NOT apply any type of aerosol spray on the GSM Mercury communication unit. Doing so 
may cause permanent damage to certain components.

While surfacing from a dive continue to breathe even if you are listening to the 
communication unit. Lung expansion injuries may result if you ascend while holding your 
breath.

Speaking  can  result  in  higher  air  consumption.  Check  your  air  supply  periodically  when 

communicating as this may affect your normal air consumption. ALWAYS MONITOR YOUR 
PRESSURE GAUGE.
Before attempting to use this device in open water you must practice using the unit in 

confined water (such as a pool).
