Mount the CPT7 on a metal surface such as the NovAtel mount adapter or the metal vehicle chassis. This
will allow heat to leave the CPT7 through contact with the metal surface and allow more optimized
performance
10.3.4 Monitoring the Receiver Temperature
If the receiver is operating in a high ambient temperature environment, you can monitor the receiver
temperature using the RXSTATUS and HWMONITOR logs.
1. Log the
RXSTATUS
log and check Bit 1 of the Receiver Status word.
LOG RXSTATUS onchanged

For information about reading the Receiver Status word, refer to
2. If Bit 1 is 0, the temperature is okay. Continue monitoring, but no action is required.
If Bit 1 is 1, the receiver temperature has exceeded the warning limit.
3. Log the
HWMONITOR
log and check the two temperature status fields (0x01 and 0x16).

Pay attention to the reading and the boundary limit status.
Refer to Table: HWMONITOR Status Table in the
HWMONITOR
log section for a description of the
Boundary Limit Status.
4. Use the suggestions in
Mitigating High Receiver Temperature
on the previous page to reduce the receiver
temperature.
5. Continue monitoring the
HWMONITOR
log to see if receiver temperature is dropping.
