Figure 2. Typical Room Layout
3.2 Placement of the PowerCom
RF1 System
The Base Station can be located anywhere in
the area where the keypads are to be used.
PowerCom RF1 keypads can operate in a room
up to 650’ x 650’ (WRS970-DSI) in size with
the base station being placed in the center of
the venue. The total range of the system is
determined by the base and keypad,
whichever is shorter. Despite a robust
communication system, walls and some other
2.4 GHz devices can moderately to severely
limit the system’s performance. If coverage of
a larger area is necessary, elevation of the
Base Station or centering in room can usually
improve the reception of the keypad signals.
NOTE: Due to the properties of signals
operating at 2.4 GHz, we do not recommend
placing any walls between the base station and
the keypads. The material in a wall tends to
absorb the RF signal and some reduced
performance might be observed.

4.1 CLR key
The CLR key is used when
connecting to a system while

operation. The CLR key can also be used
to cancel actions. In Static mode
operation, the CLR key can cancel a vote

The Send key is used to
complete multi-digit entries.
Single-digit voting does not
use the send key. The Send key is also

4.3 !/10 Key
This serves as an alert key
which can send a special
packet to the Base Station
to alert the presenter like raise hand, in
case the participant has a question or
clarification. The participant can press
this key during the slide show or out of
slide show. There will be a pop up screen
for raise hand. This key is applicable for
Likert Scale type (0 to 10) of question. If
there will be 10 answer choices for this
type of question, !/10 key is used to
choose option 10.
