HTT-B10X Troubleshooting (Continued)
TROUBLE
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
HTT-B10X is out of 
range of gateway. 
Move unit back into range.
Gateway is off.
Turn gateway on.
All LEDs blink four 
times after waking 
or button press. 
(Continued) 
Gateway changed 
channels (battery 
operation only). 
Set the gateway to a fixed 
channel (refer to “Battery 
Powered Operation” which 
starts on page 18). Reacquire 
the HTT-B10X (refer to 
“Acquire Gateway 
Connection” which starts on 
page 10). 
LEDs # 8 and #10 
are on and device 
does not function. 
Unit is in bootloader.
Cycle power by disconnecting 
the 12 Volt power pack (and 
batteries, if installed), then 
reconnecting. If this does not 
restore functionality, reload 
firmware (refer to “Programs 
and Firmware” which starts 
on page 16 for details). 
Bootloader
In rare cases, it may be necessary to bypass the HTT-B10X’s standard firmware and 
enter into the “bootloader”. This might be necessary if the unit was loaded with a 
faulty version of firmware that might prevent future firmware upgrades. In addition, 
in the event of a failed or aborted firmware upgrade, the unit will enter into the 
bootloader on its own. 
To enter the bootloader, press and hold buttons #9 and #10 while connecting the 
included 12 Volt DC power supply to the jack on the rear of the HTT-B10X. 
Continue to hold buttons #9 and #10. After five seconds, the LEDs next to buttons #9 
and #10 will flash for a half second. Hold buttons #9 and #10 for another five 
seconds to enter the bootloader. When the unit is in the bootloader (but not in Setup 
mode), the LEDs next to buttons #8 and #10 will be on. 
If you need to acquire the unit, press and hold button #2 for five seconds. The LED 
next to button # 2 will blink every half second to indicate the unit is being acquired 
by the gateway and the LED next to button #8 will indicate the link status (refer to 
“Acquire Gateway Connection” which starts on page 10 for LED #8 behavior). 
When the unit is running the bootloader, new firmware can be uploaded from the 
Crestron Toolbox. During firmware upload, all LEDs will blink. 
To exit the bootloader and restore the firmware that is currently installed, cycle 
power by disconnecting the 12 Volt power pack (and batteries, if installed), then 
reconnecting. If a previous attempt to upload firmware has failed, there is no way to 
restore. Firmware must uploaded again.
