Tips and Tricks for the Philips Pronto RF Extender LI970

Use these guidelines for optimal use of the RF function in the ProntoPro RU970

Interference:

Interference from other radio signals is the main reason why the Pronto RF may not perform well.
In most cases interference is caused by other consumer products like wireless headphones,
wireless audio speakers, wireless/cellular phones. But, microwaves and other appliances can also
disturb the RF extender. When you live in an urban area the chance of interference increases.
When the RF extender signals are interfered, the red LED on the RF extender will blink.

As radio signals are invisible it is hard to recognize the existence of the interference. See if you
can track the source of interference or, if possible, try to move the RF extender to another area.

Range:

All RF extenders are tested in the factory to receive the RF-signals from the Pronto properly at
minimal 33 m (100 ft). However, the presence of metal objects in the neighborhood of the RF
extender or Pronto will have a negative effect on the range.

Here are some tips to achieve an optimal range:

- Place the RF extender at least 1 m (3ft) from the floor. Ideally place it on your ceiling at
around 3 m (10 ft) from the floor.

- Avoid placing the RF extender and Pronto near metal cabinets or metal walls.

- Avoid placing electronic devices next to the RF extender (ie. avoid placing the RF extender

behind a TV as this will affect the range).

- Don’t put the RF extender in a warm, cold or wet environment.

- Armed concrete walls will block or weaken the RF signal.

- Using the remote control on the floor will reduce the distance range.

- Using the remote control on a metal support (table, cabinet…) will also reduce the RF

performances.

- Even your hand will influence the range. Covering the Pronto with your hand will have a
negative effect on the range.

- Experiment with different channels and extender IDs of the RF extender.

If by following the above guidelines, the RF extender is continues to perform poorly, check
if a neighbor is continuously using the same frequency band as you are. (418 Mhz +/- 1
Mhz in the US and 434 MHz +/- 1 Mhz in Europe).

Following these tips & tricks will help you to get the best out of your Pronto.
