Changing Batteries on Survey Transmitters
Battery Reordering
RF512 survey transmitters are fitted as standard with a high power 3.6V Primary lithium-thionyl
chloride C-size cell. Manufacturers part number Saft LSH14 LIGHT. Only replace with the same or
equivalent type recommended by the manufacturer. Re-Order number from Comark ‘RFBATT’.
Battery Change Procedure (Survey Transmitters Only)
• Using a suitable screwdriver undo the two battery cover retaining screws and remove the
battery cover.
• Remove the exhausted battery and replace with a fresh one taking care to snap the new
battery in cleanly without making and breaking the contacts repeatedly.
• Observe the correct polarity when changing the lithium battery.
• Replace the battery cover and do up the two screws taking care not to over tighten them.
• Observe any local restrictions on disposal of the used cell.
Check for Transmitter Errors
The removal of the battery will cause the internal clock on the survey transmitter to reset and so
generate an Error-100 condition. This will not change the performance of the device in any way, as
long as the error code does not end with the number '4' (e.g. Error-104) the device will continue to
operate as intended. Verify that the transmitter display shows either no error or an “acceptable” error
code. If any other error occurs the device will have to be returned to the Comark service department.
The RF505 does not contain a battery.
FCC Approvals
This device complies with Part 15 of the FCC Rules. Operation is subject to the following three
conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that may cause
undesired operation.
• To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the equivalent isotropic radiated power (e.i.r.p.) is not more than that permitted
for successful communication.
Transmitters must be placed greater than 20cm from the body.
