Cervis Inc. Safety Precautions
Read and follow all instructions.
Failure to abide by Safety Precautions may result in equipment failure, loss of
authority to operate the equipment, and personal injury.
Use and maintain proper wiring. Follow equipment manufacturer instructions.
Improper, loose, and frayed wiring can cause system failure, equipment damage, and
intermittent operation.
Changes or modifications made to equipment not expressly approved by the
manufacturer will void the warranty.
Owner/operators of the equipment must abide by all applicable Federal, State, and
Local laws concerning installation and operation of the equipment. Failure to comply
could result in penalties and could void user authority to operate the equipment.
Make sure that the machinery and surrounding area is clear before operating. Do not
activate the remote control system until certain that it is safe to do so.
Turn off the handheld remote and remove power from the base unit before attempting
any maintenance. This will prevent accidental operation of the controlled machinery.
Power can be removed from the base unit by detaching the 12-pin cable from the
base unit connector P1, or by removing the source power from the circuit.
Use a damp cloth to keep units clean. Remove mud, concrete, dirt, etc. after use to
prevent obstructing or clogging the buttons, levers, wiring, and switches.
Do not allow liquid to enter the handheld or base unit enclosures. Do not use high
pressure equipment to clean the handheld remote or base unit.
Disconnect the BU-2H8D base unit before welding on the machine. Failure to
disconnect the base unit may result in destruction of or damage to the unit.

Appendix A: Exposure to Radio Frequency Energy
SmaRT handheld remote units contain radio transceivers. When active, handheld remotes send
out radio frequency (RF) energy through its internal antenna.
For optimal performance and to ensure that human exposure to RF energy does not exceed the
recommended guidelines, always follow these instruction and precautions: When using the
handheld remote, hold the remote so that the top buttons are away from the body in the direction
of the base unit. Keep the remote when in use at least 15mm (5/8 inch) away from the body, and
only use carrying cases, belt clips, or holders that are approved by Cervis, Inc.
A SmaRT base unit when active sends out radio frequency (RF) through its external antenna.
Base units using an external antenna should be mounted to ensure the antenna is at least 20cm
away from the human body. Only the external antennas recommended by Cervis, Inc. are to be
used (see Table 3).

Part 1: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou
inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il
faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à
l'établissement d'une communication satisfaisante.
Part 2: This radio transmitter (LOBSRF-305) has been approved by Industry Canada to operate with the antenna type listed below with the
maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain
greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
Le présent émetteur radio (LOBSRF-305) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un

Appendix D: Typical Handheld to Base Unit Communication
Handheld remote and base unit communications are established at Cervis before shipping when
systems are ordered. However, it may be necessary to establish or re-establish communication
between a remote and a base unit at some point. The Associate procedure is used to do this.
A standard SmaRT System consists of one handheld remote and one base unit. Each base unit
is capable of communicating with up to eight handheld remotes. Each handheld must first
establish a communications link with the base unit before the base unit will recognize the
handheld unit. This process is called Associate.
In some cases it may become necessary to break the communication link between the handheld
and the BU-2H8D. This process is called Dissociate. Be aware that when a handheld is
dissociated from a base unit, all communication links to that particular base unit are erased from
the base unit memory! For instance, a particular BU-2H8D is associated to Handheld Remotes 1
through 5. Remote 2 dissociates—breaks the communication link—from the base unit. All five
handheld remotes are removed from the base unit memory. The Associate procedure must be
used by any handheld that now needs to control that BU-2H8D.
The following Associate and Dissociate procedures are general methods of associating or
dissociating Cervis handheld remotes to the BU-2H8D. Custom systems may have different
Associate methods unique to the custom system design.
D1: BU-2H8D/PTO-DO-OO Remote Communication
To Associate
The base unit and handheld must be OFF prior to attempting to associate. Base unit and
SmaRT 2, 4, and 6 button handheld association is established using the following steps:
1. Remove power from the base unit and turn off (PTO –time out) the hand-held device.
2. Stand near the base unit in unobstructed, clear line-of-sight with the handheld in hand.
3. Simultaneously press and hold the Associate (B1) and Dissociate (B2) buttons. RX and ER
light.
4. Continue to hold both buttons until TX and RX light steady.
5. When TX and RX light, release B1 and B2. ER and BA light.
 Note: If the next button press is not immediately performed (approximately 2sec.), all LEDs
flash and the Associate procedure is aborted. The process must be started anew to establish
the communication link.
6. Immediately press and hold the Associate button (B1). All LEDs light.
7. TX begins to slowly blink. Continue to hold
B1.
8. Apply power to the base unit.
The handheld and base unit begin to establish
a communication link while the Associate
button is held. Once the process is complete,
all LEDs light briefly and then go out.
9. Release the Associate button. The SmaRT
System is ready for use with that particular
handheld remote.

To Dissociate
In some circumstances it may become necessary to break the communication link, or dissociate
a base unit and a PTO handheld remote.
Using the following steps will break all previously established handheld remote
links. It will be necessary to perform the Association Procedure (Heading 0 above)
using each handheld to re-establish communication links with a base unit.
1. Remove power from the base unit.
2. Stand near the base unit in line of sight with the handheld in your hand.
3. Press and hold both Associate (Button 1) and Dissociate (Button 2; see Figure
8). RX and ER light.
4. Continue to hold both buttons until TX and RX light steady.
5. When TX and RX light, release B1 and B2. ER and BA light.
 Note: If the next button press is not performed within the two second interval all LEDs
flash and the procedure is aborted. The process must be started anew to break the
communication link.
6. Press and hold the Dissociate button B2. (See Figure 8 above.) All LEDs light.
7. TX begins to slowly blink. Continue to hold B2.
8. Apply power to the base unit while continuing to hold the Dissociate button.
The base unit and all previously linked handhelds begin to Dissociate communication links.
Once the process is complete, all LEDs light briefly and then go out.
9. Release the Dissociate button.
The SmaRT base unit will not communicate with any handheld remote units. A handheld remote
must use the Association Procedure (Heading 0 above) to re-establish a communication link with
the base unit.
