Installing a Radio Pack Battery
Before powering on an RP, install its battery by doing the following:
1. Hold the RP at a 45-degree angle, pointing the bottom end down. Then, depress and hold the RP’s belt clip
down.
2. Lift open the battery door and remove it.
3. While still holding the RP at an 45-degree angle and depressing the belt clip, install a fully charged Lithium-
Polymer rechargeable battery or three AA batteries in the RP. Take care to insert the battery with the contacts
facing down into the RP and oriented such that the contacts on the battery will line up with the contacts inside the
RP battery compartment.
4. Place the battery door back on the RP, making sure to align and insert its tab at the top first, and then secure the
door by pressing until it clicks. (Secure a magnetic door by pressing firmly until the magnet engages.)
5. Turn on the RP by pressing and holding the Power button on the back of the pack for 3 seconds.
Note:
The RP will not operate unless it has been paired to a Control Unit; if it has not been paired it
will indicate “No Pairing Information Available” on the pack’s display. In addition, the RP will not
communicate if its CU And RTs are not yet online. CoachComm recommends powering on the
CUs and RTs first before powering on the RPs.
Pairing an RP to a Control Unit
RPs must be paired to a Control Unit (CU) before they can operate with your X-System. Once RPs are paired to a CU,
this process does not need to be done again unless the RP is being paired to a new or different CU (for example, after a
replacement is made for repairs). An RP may be paired without installing a battery, if required. In this case, the CU will
provide power to the RP during the pairing process. If no battery is installed, the RP will power down as soon as it is
disconnected from the CU.
•
Compatibility Note:
To work together as a system, all connected devices must have firmware that matches the
version installed on the top (master) CU. See the Firmware Update procedures on page 76 for more information.
•
Limit of Active RPs for systems with more than three Radio Transceivers (RTs)
: A maximum of 18 900MHz
and 18 2.4GHz RPs may be active on X-System because each RT allows 6 RPs. Since only 18 RPs can be active
on a single CU, you should pair 900MHz RPs to the top CU, and pair 2.4GHz RPs to the bottom CU. If you have
more than 18 RPs in either frequency, you can pair the extras to the appropriate CU, but those extras will not
display as “active” until you remove one of the original 18 active RPs.
