FastFacts 2.1: Getting started

2.2 Unpacking and connecting

Carefully unpack the RM500SL and check the contents of the shipping box against the enclosed packing list. Note that some parts may be packed inside the test chamber.

2) Unwrap the power cord from its stowage hooks - noting carefully how it has been packed. To avoid serious damage to the display screen, always

repack the cord this way.

3) Connect the power cord to the socket next to the power switch on the right side of the unit. Plug the other end into a grounded 100 – 240 volt power outlet.

FastFacts 2.2: Unpacking and connecting

0611 RM500SL User’s Guide Version 2.8 Page 10

2.3 Microphone connection

Battery pills are optional

. The

thin connecting strip

each battery pill

1) DO NOT twist the cable when attaching a coupler to the coupler microphone.

Turn only the coupler or unplug the coupler microphone before turning it.

2) DO store the coupler microphone in its mounting clip when transporting.

3) DO make sure that the 2cc coupler is tightly screwed to the coupler microphone when performing hearing instrument tests. Coupler leakage can cause feedback and erratic response curves.

4) DO ensure there are no cracks in the #13 tubing on the BTE (HA-2) coupler.

5) DO replace the tubing on the BTE coupler with 3/8” (10 mm) of #13 tubing.

Probe microphone:

1) DO NOT reuse probe tubes. Debris and liquid from cleaning attempts can

lodge in the enlarged base of the probe tube and subsequently clog the probe microphone port.

2) DO NOT attempt to open or repair the probe microphone. Attempting to repair the probe module may lead to damage or alteration of the factory calibration.

3) DO keep the probe module and probe tubes in a clean area.

4) DO stow the probe module when not in use or when transporting the RM500SL.
