For example, if the calibration process measures temperature to within ±0.1°C, then the MK8 calibrated accuracy would be:
- For 0.4 deg resolution option
±(0.6deg + 0.1deg) = ±0.7degC (±20°C)
±(0.9deg + 0.1deg) = ±1.0degC (±40°C)

- For 0.1 deg resolution option
±(0.15deg + 0.1deg) = ±0.25degC (±10°C)

MK11/12 Transmitter General Specifications

MK-11 and MK-12 beacons are microprocessor controlled pulsed-CW transmitters, designed for operation within the 137 - 225 MHz frequency range. Each MK-11 beacon transmits on a single, field-programmable frequency (within the frequency range that is ordered). MK-11 beacons also support 3 field-programmable power levels. The MK-12 beacon is crystal based, and therefore each beacon is built to operate on a specific frequency and with a specific power output (four power levels to choose from when ordering).

Available Sensors
• Motion Sensor (3-axis accelerometer) - Option 500

- Activity - Used to determine the level of activity of the study animal. The animal's motion is sensed once each second to determine "active" Classification Periods (programmable in length). At the end of a programmable Update Period, the number of "active" Classification Periods is used to establish either: a) one of two programmable, fixed pulse periods (i.e., Low activity level, or High activity level), or b) to control a variable pulse period that defines the measured amount of activity.

- Mortality - Provides an "active/alive" or "inactive/dead" pulse period depending on the activity level of the study animal. Motion is sensed once each second and a tally is made of "active seconds" over a programmable period of time (the Mortality Period). If the count of "active seconds" over this period of time is below a programmable threshold, the animal is deemed dead and the unit transmits a programmable, fixed pulse period. Otherwise, the animal is considered alive, in which case, the unit transmits according to its normal programmed behavior. This can alternatively be used to trigger the "Time Since Event" function.

• Temperature Sensor

- Temperature measurement - Temperature is measured via the sensor specified when the unit was ordered/built (see table below). The temperature is measured at a programmable time interval, and is used to control a variable pulse period.

- Mortality - Temperature is measured via the sensor specified when the unit was ordered/built. (Default is Opt. 400, centered at 37°C.) When the temperature is below a programmable value, the animal is deemed to be dead, causing the unit to transmit at a programmable, fixed pulse period. Otherwise, the animal is considered to be alive, in which case, the unit transmits according to its normal programmed behavior. This can alternatively be used to trigger the "Time Since Event" function.

Service Commitment

Since 1970, Telonics has built a reputation based on product quality, product support, service, and customer satisfaction. Telonics strives to produce the highest quality products, and to support those products accordingly.

Because of extreme conditions and the unpredictable nature associated with most telemetry applications, problems occasionally arise. Most problems can be resolved quickly. In all cases, we hope to be able to work in partnership with users to resolve problems to the user's satisfaction and to uphold our demonstrated commitment to excellence. If problems should arise, all products must be returned to our factory for failure analysis.

Warranty: VHF Transmitting Subsystems

The VHF Transmitting Subsystem includes the following main components: internal digital and radio frequency electronics comprising the transmitter, power supply (battery), exterior packaging, transmitting antenna and attachment. A refurbished Subsystem is warranted as if the Subsystem was purchased new, unless otherwise stated.

Telonics warranties only the following with respect to the Subsystem:
1.1 The internal electronics (excluding batteries) are warranted to be free from defects in materials and workmanship and to perform to the operational specifications over the specified operating temperature range as published by Telonics for the rated operational life of the Subsystem (as recorded on the final test data sheet accompanying the unit), up to a maximum of three (3) years from the date of initial shipment of the Subsystem by Telonics.
1.2 The exterior packaging integrity of hermetically sealed subsystems are warranted for the full operational life of the Subsystem, up to a maximum of three (3) years from the date of initial shipment of the Subsystem by Telonics.
1.3 The exterior packaging integrity of polymerically sealed subsystems are warranted for the operational life of the Subsystem, up to a maximum of one (1) year from the date of initial shipment of the Subsystem by Telonics.

Limitations:
Although each Subsystem is supplied with a power supply in the form of a battery, Telonics does not manufacture batteries (electrochemical cells), and therefore cannot warranty the battery lifespan, mechanical integrity or other battery performance issues. However, Telonics conducts extensive testing of all types of electro-chemical subsystems to determine suitability to the application. Once an electrochemical system is chosen for a configuration, testing procedures are employed at Telonics to evaluate every individual battery that is installed in each transmitting subsystem. Even using these advanced testing procedures it is not possible to determine a specific battery's lifespan or mechanical integrity.

Telonics conducts tests to assure that each unit is transmitting at the power level selected by the user. Actual range performance is a system characteristic dependent upon numerous conditions including receiver sensitivity and noise figure, receiving antenna tuning and pattern, transmitter antenna integrity, line of sight conditions in the field, and vegetation and habitat conditions and other factors specific to individual study sites. Therefore it is not possible to warranty a minimum range that will be achieved for units deployed in the field.

"Packaging integrity" as applicable to 1.2 and 1.3 above, is limited to normal wear as encountered on the animal.

It is the purchaser's obligation to make certain that it orders the correct size and type of Subsystem for the particular type and size of animal that the Subsystem will be applied to, and no warranty is expressed or implied for any failure to meet operational specifications due in whole or in part to use of an incorrect size or type of Subsystem.

No warranty is expressed or implied with regard to abnormal events or damage due to human actions such as gunshot damage, vehicle encounters, etc. Further, no warranty is expressed or implied with regard to damage resulting from misuse, accidents, unauthorized service, extreme conditions, or other causes not specifically enumerated herein.

The entire risk, as to the results and performance of the Subsystem, is assumed by the customer. Neither Telonics, nor its suppliers, shall have any liability to the customer or any other person or entity for any indirect, incidental, special, or consequential damage whatsoever, regardless whether Telonics has been told of the possibility of such damages or that such damages might be foreseeable. Telonics has no responsibility or liability for the claims of any third party. Telonics' and its suppliers' maximum aggregate liability shall not exceed the amount paid by the customer for the Subsystem.
