3.4. Use without CUR-3
The TMR880i RC-9 can be used without the external control unit CUR-3, for example as a
modem. In this case, the radio unit can be powered on/off by the IGS line (see pin 20 of system
cable). If there is a power outage when the IGS line is active, the radio unit starts up again
automatically.

4.1. Handset (HSU-6)
Figure 5. Handset HSU-6 (left) and phased-out model HSU-1T (right)
In the following figure, the handset is connected to the system cable CA-105, and can be
used. Check the Taqto parameter settings to support the more flat audio profile made for
HSU-6.
HSU-6
Figure 6. Connected handset HSU-6
4.2. Handsfree microphone (HFR-1)
The handsfree HFR-1 microphone is connected to the system cable CA-105 with a 3.5mm jack.
The direction and distance to the user should not exceed 40 cm. Avoid wind noise positions in
the vehicle.
When installing the Audio HF-Mic Jack connector, add 1.5 round of electronics tape to cover the
connectors to avoid the connection becoming loose when the vehicle vibrates.

4.12.3. Start-stop plug (SS-4)
The TMR880i RC-9 radios manufactured before 2021 and used with end-to-end encryption
(E2EE) smart cards must have a SS-4 plug connected to the programming connector in the
system cable. This plug is needed only if the E2EE feature is used (Smart Card).
For radios produced later, there is no need for the plug. However, if the plug is accidentally
connected to a new radio, it does not cause harm to it.
