2. This device may accept any interference
received, including interference that may cause
undesired operation.

FCC Section 15.105

This equipment has been tested and found to
comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection
against harmful interference when the equipment is
operated in a commercial environment.

This equipment generates, uses , and can radiate
radio frequency energy and, if not installed and
used in accordance with the instruction manual, may
cause harmful interference to radio communications.

Operation of this equipment in a residential area is
likely to cause harmful interference, in which case
you will be required to correct the interference at
your own expense.

SAFETY

Information for the user

Beware of unexpected movement. The user
should remain outside of the full working
envelope of probe head/extension/probe
combinations.

Handle and dispose of batteries in according to
the manufacturers recommendations. Use only
the recommended batteries. Do not allow the
battery terminals to contact other metallic
objects.

In all applications involving the use of machine
tools or CMMs, eye protection is recommended.

Refer to the machine supplier’s operating
instructions.

Information for the machine supplier

It is the machine supplier’s responsibility to
ensure that the user is made aware of any
hazards involved in operation, including those
mentioned in Renishaw product documentation,
and to ensure that adequate guards and safety
interlocks are provided.

Under certain circumstances the probe signal
may falsely indicate a probe seated condition.
Do not rely on probe signals to stop the
machine’s movement.

RMI visual diagnostics

RMI visual diagnostics

A visual indication of system status is provided by LEDs.
Status is continuously updated and indication is provided for
START, LOW BATTERY, PROBE STATUS, ERROR, SIGNAL STRENGTH

LED LIGHT SIGNALS

1. LOW BATTERY / START

Red Battery is low.
Green M code start/stop in

progress.

Yellow Battery low and M code

start/stop in progress.

Off Battery is OK (and no

M code start/stop in
progress).

2. PROBE STATUS

Red Probe triggered or

unknown status.

Green Probe is seated.

RMI visual diagnostics

3. ERROR

Red Error, other outputs may

be incorrect.

Off No Error.

4. SIGNAL

Green Excellent communications.
Yellow Good communications.
Red Poor communications,

radio link may fail.
Off No signal detected.
Green/off Flashing: RMI is in

acquisition mode, and can

acquire a partner RMP.
Red/yellow Flashing: RMI has (just)

acquired a new partner RMP.

Notes.

1. The probe status LED will always be
illuminated when power is present.
There is no ‘power present’ LED/light.

2. All the indicators repor t the status of the
partner RMP60. If there is no partner in
range, or the partner is off then the probe
status and error LEDs will be red and the
other LEDs will be off.

3. When the RMI is powered it will enter the
acquire partner mode which will be indicated
by the flashing green signal LED (no change
in outputs). After a short time (~12 secs) it
will switch to its normal mode listening for
its partner.

4. The conditions shown by the low battery,
probe status and error LEDs are the same
as those present on the electrical signal
outputs.
