Notice!
Connections to both antenna connectors (secondary and primary) must be installed using the
supplied antennas or an extended antenna (sold separately). Failure to do so might cause
poor signal strength.
When using an external antenna such as the Bosch Multiband Antenna (B40-P, B40-MB25 or
B40-MB50) connect the cable to the primary connector of the B444-A/V cellular module. You
must also connect the supplied antenna to the secondary antenna connection. Failure to do so
may result in poor service and dropped signals or connection.
