SF503UL and SF504UL Pendants *Repost*

Storage Mode Reminder


TekTone SF503UL and SF504UL pendants are equipped with two batteries, a user-replaceable coin cell, and an internal battery that is not user serviceable. When a pendant will not be used for an extended period of time, the pendant must be placed into storage mode to prevent depletion of the internal battery.

Storage mode is an ultra-low battery state designed to protect the life of the internal battery for up to 12 months. The pendant is shipped from TekTone in storage mode. The pendant will also automatically go into storage mode at the next check-in transmission time if the coin cell battery has been removed.

Note: When the pendant is in storage mode, it will not transmit alarms or check-in messages.

If a pendant will not be deployed to an end user for more than 12 months from the date of manufacture that appears on the pendant or pendant packaging, you must install the coin cell battery and press the button before the 12 months elapses to ensure proper operation.

If the pendant has remained idle for more than 6 months, we advise a 72-hour charging period before deploying the pendant to an end user. If the pendant remains unused after installing the coin cell battery, it will operate for approximately three years, assuming no button presses.

Placing pendants in Storage Mode: First, remove the pendant from the Tek-CARE system configuration if it has already been installed. Use an alarm clearance card or a quarter to turn the battery cover to the unlocked position. Remove the battery from the battery compartment. Press the activation button for at least one second. The red LED will flash, and the pendant will vibrate briefly to indicate that an alarm has been sent. This serves as confirmation that the pendant is now in storage mode. Seat the battery door over the empty battery chamber, and replace the battery cover.

Pendants must not be left in storage mode for more than 12 months. Pendants should be stored in ambient conditions (69°F to 73°F or 20°C to 23°C).

Note: If the alarm activation button is pressed when the pendant is in storage mode, and the battery is not installed, a yellow LED will illuminate briefly on the lower portion of the pendant to indicate a missing battery condition to the user. If this yellow LED does not illuminate without the main coin cell battery installed, the internal battery has been depleted, and the pendant must be replaced.


TekTone Technical Support Group

A family-owned business committed to providing quality intercommunication solutions at competitive prices, supported by conscientious customer service, for the Health CareResidential, and Commercial markets.

Ambulatory surgery centers (ASCs) are health care facilities that offer patients the convenience of having surgeries and procedures performed safely outside the hospital setting. This trend in healthcare is a growing new market and TekTone has designed our systems to offer valuable nurse and emergency call capabilities to ASC patients.


Continuing Care Retirement Communities (CCRC), also known as Life Plan Communities, are designed for seniors who are currently living independently, but want the safety and security of being cared for as they age without having to relocate. As a resident’s health declines, he or she may transition from an independent living residence to assisted living, to an intermediate or skilled nursing facility—all on one campus. TekTone offers systems specialized in adapting to the changing needs of CCRCs, while keeping resident’s safety and security a top priority.


A skilled nursing facility (nursing home, convalescent home, care home or rest home) provides a place of residence for those who require continuous nursing attention. Services available in skilled nursing facilities include assistance of nurses, nursing aides and assistants; physical, occupational and speech therapists; social workers, recreational assistants; and living space. In some instances, residents may reside in skilled nursing facilities to receive rehabilitation or other therapy following an illness or accident.


Assisted living / independent living facilities usually have a campus-wide call system so a resident can notify caregivers by initiating a call from a personal pendant or emergency button press/pull. The systems specified for these types of facilities are usually referred to as emergency call systems or personal emergency response systems. Call system requirements in assisted/independent living vary, but may be mandatory in some states. Assisted living facilities may prefer a combination of Tek-CARE wireless and wired technology, with pull-cord stations, call buttons and wireless pendants to ensure staff members are notified efficiently and quickly.


Nurse call systems for hospitals, microhospitals and cancer centers must offer more than the ability for a patient to call for a nurse. These systems are now about total solutions to improving facility performance. Performance is identified as improving efficiency in terms of facility goals (rounding, reducing time to answer calls, tracking staff performance using metrics), improving staff satisfaction, and improving patient satisfaction.


Nurse call systems in high security facilities, such as psychiatric and behavioral health facilities, require the implementation of advanced features to protect against vandalism and to provide accurate monitoring and reporting options.


TekTone‘s National Accounts Program is specifically structured for organizations that have multiple facilities. Whether you are a local, regional or national organization, our national account program provides you with high quality healthcare communications and a world-class service network.



The Tek-CARE platform provides customizable communication solutions for all types of healthcare facilities. TekTone’s wired and wireless nurse call systems provide flexible features and integrations to assist staff members in providing the greatest care for residents. In addition to the safety and security provided by the nurse call system, TekTone also offers the Tek-CARE Wander Management system to help keep at risk residents away from harm and Fall Detection and Monitoring offering peace of mind for caregivers, residents, and their loved ones. With the Alert Integration Manager, these systems can be integrated to display calls at one convenient location, as well as provide customized management reports. Along with reporting, the Tek-CARE Staff App can be used to notify staff on-the-go using iOS or Android devices or display monitors using Tek-CARE TV.



TekTone’s roots lie in the manufacturing and design of apartment entry systems. With multiple station options, custom engraved panels and retrofit capabilities, Tek-ENTRY apartment systems provide a convenient and reliable communication path for residents. Also available is the Tek-SAFE Area of Rescue Assistance System for areas out-of-reach of communication in the event of an emergency.
