1.8 Warnings And Cautions This symbol is used to indicate a WARNING. These highlight potentially harmful (to the patient or operator) situations. This symbol is used to indicate a CAUTION. These are conditions which may lead to equipment damage, malfunction or inaccurate operation. WARNING
The Siesta should not be used in the presence of flammable liquids or gasses. This may present an explosion hazard. Do not connect sensor lead wires into electrical outlets. Lead wire contact with electrical outlets presents a serious shock hazard. Pacemaker Patients – Heart rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon heart rate meters. Burns may occur at the electrode sites when the Siesta is used in conjunction with high frequency surgical or diathermy equipment due to high frequency currents flowing in the electrode lead wires. To minimise this risk: ●

The equipment is not serviceable by the User's service personnel. The Siesta should under go regular electrical safety testing in accordance with your hospital's medical equipment routine testing procedures. This should be done at least annually. The Siesta does NOT have defibrillator protected patient circuits. If the patient needs to be de-fibrillated, remove all patient connected leads from the Siesta before activating the defibrillator. This product contains batteries which must be disposed of properly. Local, state or national laws my prohibit disposal of batteries in ordinary trash. Consult your local waste authority for information regarding available recycling and/or other disposal options. All external devices must be connected to the Siesta expansion ports prior to making any patient connections to the Siesta. Failure to do so may present a patient safety hazard. Do not connect unterminated interface leads to the Siesta. Doing so may present a patient safety hazard. CAUTION
Operation may be affected in the presence of strong electromagnetic sources such as electro surgery equipment. Remove any batteries from the Siesta if the equipment is not likely to be used for some time. The Siesta must be powered off before connecting or disconnecting external modules or the XPOD oximeter from the expansion ports. Failure to do so may damage the Siesta.

1.9 Prescription Device CAUTION
U.S. Federal law restricts this device to sale by or on the order of a physician.
1.10 Placement of Equipment Do not operate the Siesta near flammable or explosive gases or materials.
1.11 Interference The Siesta records physiological electrical signals which can be influenced by external electrical interference. Filtering techniques can be used to reduce the impact of external sources of interference. However, by being alert to signal interference, the potential effect of interference can be minimised. Keep the Siesta at least one metre (three feet) away from all electrical appliances. Examples of these include TV sets, electric blankets, air conditioners, microwave ovens, cordless and cellular telephones and walkie-talkies. Interference to physiological signals could be caused by strong transmitter signals such as TV, radio, airport, police, fire and ambulance stations. If recording will occur within two kilometres (1.3 miles) of one or more of these sources, then ask Compumedics Product Support to help you to determine if your system will operate properly. Synthetic fabric from draperies or carpets can cause interference due to static electricity. Touching an electrically conductive and earthed object before handling the patient or the Siesta can prevent interference from static charges.
1.12 Manufacturer's Recommendations Use only Compumedics supplied accessories with the Siesta. Be sure to read, understand and follow the instructions in this User Guide and others that come with the system and its components. Page 6
