Remove the cover

Using the tool provided, loosen and remove the 4 screws at the base

of the transmitter. Grasp the cover and pull away from the

base. This operation may be easier if the transmitter remains

attached to the HP port of a regulator. Ensure no pressure

is present at the HP port during the battery

CHANGING THE BATTERY

Battery + change operation.

Exchange the battery, Remove the existing battery from the battery clip. Dispose of the battery properly according to local regulations.

It is recommended to leave the battery out for at least 1 minute to allow internal circuits to reset. Insert a new battery, negative towards the base, positive towards the top (a small + is marked at the top end). Push the battery down gently in to the clip. The status LED sequence red, yellow, green shows good battery contact.

Replace the cover

Ensure the base o-rings are clear of debris and are not damaged. Replace o-rings (see specifications page for dimensions) if damaged, using a small amount of O2-compatible lube. Carefully align the cover so the circuit board fits in the wide part of the case. The cover should slide down easily until the base o-rings engage. Do not force the cover down if it is not aligned.

Press the cover down firmly until the screw holes line up with those in the base. Using the tool provided, replace the 4 screws and tighten to a snug level.

Caution: Do not over-tighten screws. Screws should be tightened to a maximum of 3 in-lb to prevent damage to the screw heads.

Check Transmitter Operation

To ensure the new battery is installed properly and the Swift is working, install the regulator on a scuba cylinder and pressurize the system.

Check that the pressure reading is reporting correctly.
