The accessory interface is provided by Bluetooth and Reduced Function PopPortTM. RH­51/52, RH-67/68 has a PopPortTM connector but no ACI interface internally, so it’s called
the RF PopPortTM.

RH-51/52, RH-67/68 uses the same connector as another PopPortTM phone but it can’t
communicate with ACI accessory. Monoural headsets, charger and camera flash are

interfaced via the RF PopPortTM and BT headset, and some BT accessories are interfaced
via Bluetooth.
