SBO Remote Control Radio Model - Quick Installation Guide
Radio Model N ame: RCRM
The RCRM is a module intended for Remote Control devices. It is equipped with a micro processer host and a short range low power radio system including a PCB
loop antenna on board at the same printed circuit board (PCB).
Besides the host and the radio system the module also includes a power management circuit, battery connector, 3 switches, and small discrete components.
When the RCRM is mounted inside the plastic shells of a remote control device, t hen the
whole product shall normally be hand held or placed on a table, when the user has one or
two wireless hearing aids on the ears, also running at a radio frequency of 3.84 MHz.
The radio system inside the module is a low power, inductive radio transmitter working
at 3.84 MHz and consisting of (see illustrations next page):
- A TX circuit and
- A 7.68 MHz crystal
The low power, inductive radio transmitter is consisting of an “AND” and an “XOR”
gate making the modulation fed with data from the host, a clock oscillator and two
switching transistors feeding the modulated RF signal at 3.84MHz to the PCB loop
antenna.
The module mounted inside a plastic shell is shown to the right:
NB: The RCRM is intended ONLY for SBO Hearing and OEM branded products
intended for remote control of hearing aids at 3.84 MHz. If used for other types of products or systems, SBO Hearing cannot guarantee continued
conformance with FCC part 15 regulations. Because of this and due to limited shielding of the module, the RCRM is approved only with a limited
modular approval.

Guide
Radio Model Name: RCRM
The RCRM with all its mounted components is intended to be installed as a
module into SBO Hearing Remote Control devices, (e.g. the Oticon RC-2A)
or similar OEM branded products (like Bernafon).
The module requires two AAAA batteries to be mounted in an external
plastic shell (as shown on the previous page). Key presses are wirelessly
transmitted to connected devices (e.g. Oticons wireless hearing aids).
The module has both its voltage regulators on board.
The module PCB is depicted to the right with its main components and
connections:
