The FHF FernTel 3 is an analogue, weather-resistant telephone in black/yellow finish without display, designed for use in indoor and outdoor environments. The device features a robust construction made of polycarbonate and is suitable for wall and desk mounting. It is particularly suitable for environments with high mechanical stress, humidity or seawater exposure, with protection class IP65 ensuring high resistance against dust and water jets. The yellow and black colour scheme ensures good visibility, especially in industrial or public areas.

Applications
This telephone is designed for use in outdoor environments as well as indoor spaces with increased requirements for environmental resistance. The IP65 protection class makes it suitable for locations such as production halls, warehouses, port facilities, parking garages or public institutions, where the device may be exposed to mechanical stress, humidity or splashing water. The temperature resistance from -25 °C to +55 °C extends the application range to regions with extreme climatic conditions.

Functions and Equipment in Detail
The device features a rubber keypad designed for long-term use under harsh conditions. The handset cord is made as a steel-reinforced armoured cord, providing high mechanical strength and protection against cutting. An integrated hearing amplifier with two stages allows volume adjustment to suit different environmental conditions. The ring tone is approximately 95 dB(A), ensuring good audibility even in noisy environments. The telephone does not feature a hands-free function or a headset connection. The number of memory keys is zero.

Technology Explained Simply
The telephone operates on the analogue network, meaning it is connected via a conventional telephone line and does not require an IP or internet connection. The IP65 protection class means the device is dust-tight and protected against water jets from any direction – making it suitable for outdoor use or in damp indoor areas. The polycarbonate housing is resistant to mechanical impact and UV radiation, extending its lifespan in outdoor environments.

Compatibility and Accessories
The telephone is designed for wall and desk mounting, with the desk version supported by a handset rest secured with two screws. The delivery includes the telephone, a telephone holder, the handset rest with two screws, and four washers. A manual is also included in the delivery scope.

Mounting and Installation
Mounting is done either on a wall using the included holder or on a desk using the handset rest. Installation requires an analogue telephone line. The necessary mounting elements (screws, washers) are included in the delivery scope. Mounting can be done without special tools or additional components.

Operational Advantages
The FHF FernTel 3 offers high reliability in harsh environments. The robust construction, weather-resistant design and high ring tone volume ensure continuous functionality. The simple operation without display and memory keys reduces complexity and increases ease of maintenance. The use of polycarbonate and rubber for housing and keypad ensures long service life under industrial conditions.
