Recharging the Battery Pack
NiCad battery packs are shipped from the factory discharged. Prior to the
first use, charge the battery pack while it is disconnected from the
Communicator. Subsequent charges may be performed while using or
storing the HART Communicator, without removing the battery pack.
NOTE: If the HART Communicator is stored for an extended period of time,
or the battery pack becomes completely discharged, remove the battery
pack from the Communicator and recharge it separately prior to using.
To recharge while using the Communicator, plug the recharger into an AC
outlet or powersource. To recharge while storing the Communicator, plug the
recharger into an AC outlet or power source, make sure the HART
Communicator is off, and charge for 16 hours. Overcharging will not harm
the Communicator battery pack.
NOTE: For optimum performance, periodically discharge (use battery power
until the low battery icon appears) and then fully recharge the battery pack.
Using a Memory Module
The HART Communicator is supplied with a replaceable Memory Module
(Figure 1-44). A 12 MB Memory Module is the recommended standard.
The Memory Module is programmed to communicate with specific HART-
compatible devices. Refer to Reviewing Installed Devices on page 1-12 to
find the specific HART-compatible devices that are programmed into your
Communicator’s Memory Module.
If you find that some specific devices are not listed in your Memory Module,
contact your nearest service representative. Your Memory Module may be
reprogrammed or replaced to include support for the required HART devices.
Explosions can result in death or serious injury. Do not recharge the NiCad
battery pack in an explosive atmosphere.
