To replace the optional VSWR module, proceed in the following order:
Unscrew the two M3x10 counter-sunk head screws underneath the rear side of the
modem plate.
Cutting the cable tie is not necessary if you carefully disconnect the USB
connectors and RF cables before taking out the module.
Note: Make sure to remember their correct positions according to the
RF connectors labeled with FWD (Abbrev. for FORWARD - left) and
REV (Abbrev. for REVERSE - right), see following illustrations:

Insert the new VSWR module and proceed in reverse order, i.e. fasten the two
screws again from below and reconnect the USB and RF cables.
Note: Be careful with the RF connectors! Do not confuse REV and FWD
connectors! Ensure to re-connect the FWD-RF connector and cable to
their correct positions before the replacement, (as illustrated in figure
