1. by how much the sensitivity has changed When the sensitivity has been changed by the required numbers of steps to a new value the paddle should be turned back to normal operational mode to check the new lever sensitivity 9a5n mail inet hr Nenad Rotter 9A5N To stop the software algorithm for lever sensitivity adjustment push the on off button until the LED turns on which indicates normal paddle mode operation You can then check the new lever sensitivity If the required sensitivity has not been achieved repeat the adjustment procedure as many times as necessary The value of the lever s sensitivity is permanently saved in the microprocessor s EEPROM and will not change until adjusted again 6 Auto switch off If no paddle lever is pressed for approximately 40 minutes the Solid State CW Paddle will switch off automatically 7 Contest mode S N MMXIV 052 and up During CW contests paddles are used infrequently but should be permanently ready 24 48 h to commence immediate keying As paddles may also be unused for periods longer than 40 minutes the Auto switch off function should be temporarily disabled Procedure 1 Switch off paddle if it is not already off 2 Push the on off button and keep it pushed 3 The LED will turn on start blinking 2 seconds later 4 Release the on off button 5 The LED will turn on and stay on This indicates that the paddle is in contest mode and will remain so unless the user swi2. diminished keying will be less fatiguing and more enjoyable The Solid State CW Paddle has two major parts head and base The paddle brain based on microcontroller technology is situated in the head which is made of aluminum to protect sensitive electronic components from the effects of RF signals The paddle base is a piece of stainless steel coated steel with a mass of 1 5 kg The total paddle mass of 1 8 kg gives outstanding paddle stability on flat surfaces during keying In order to generate CW code an external keyer or a transceiver with built in keyer must be used The Solid State CW Paddle is available in a single and twin lever version ATTENTION Avoid exposing the paddle lever s to any excessive pressure or shock Excessive pressure can drastically reduce the lifetime of sensors internal to the lever s while stronger shocks can cause permanent damage 9a5n mail inet hr Nenad Rotter 9A5N 2 Before you begin The Solid State CW Paddle is delivered without batteries and an interconnection cable mainly due to the paddle s shipping weight In order to keep the paddle as heavy as possible and still limit the mass to a maximum of 2 kg for delivery as a registered letter to your address no batteries or cables are included in the package In order to prepare the Solid State CW Paddle for operation you will need to obtain the following e battery AAA LRO3 type 2 pcs e an interconnection cable The install
3. 5 mm 3 pin stereo socket for connection with external devices such as a keyer or transceiver with a built in keyer For interconnection between the Solid State CW Paddle and an external device a two wire shielded cable must be used Users can easily make their own cable to the required length To use one cable end must go into the Solid State CW Paddle s 3 5 mm 3 pin stereo phone plug The plug pin outs are Tip left lever or left side of single lever normally Dot out Ring right lever or right side of single lever normally Dash out Shaft common At the other cable end the type of plug and pin outs depend on the device to be used You may want to consult the device user manual for these details In most cases where the pin outs are the same on both the paddle and the external device prefabricated shielded audio cable with a 3 5 mm stereo plug on both ends can be used If the external device has a 6 3 mm paddle socket a stereo adapter from 3 5 mm to 6 3 mm may be used Some telegraphers may prefer to use a reversed Dot Dash paddle configuration If this is the case the interconnection cable should be reversed at one end It is also possible to use a straight cable with the external device set to a reversed paddle configuration The Solid State CW Paddle outputs are of semiconductor type Outputs will work properly if a positive voltage to common is present on the Dot and Dash line Most ele

5. ation of the battery and interconnection is described below The button on the right side of the paddle is the on off switch The paddle status is indicated by a blue LED behind a white window under the lever s The button acts as a toggle To switch the paddle on push the button until the LED turns on To switch the paddle off push the button until the LED turns off The switch off action takes around 0 5 second to avoid involuntary paddle offs Remember to retain your original Solid State CW Paddle box for future transport e g portable operation DX expeditions etc and or for secure paddle storage 3 Finger piece and or battery installation If your paddle is sent to you via post the finger piece s are not mounted on the lever s to avoid lever sensor damage during shipment and batteries are not inserted due to postal service safety regulations As finger piece montage on lever s and battery insertion can be done at the same time the procedure below describes both To reach the battery compartment it will be necessary to separate the paddle base and head which are connected together with 4 screws In addition the installation of the finger piece s is safe and easy when the paddle base and head have been separated For this task you will need a Phillips screwdriver a magnetic tip is recommended and a book that is at least 5 mm thick A hex key for finger piece screws is attached Note that a finger piece once attach
6. ctronic keyers and transceivers have 5 V present on Dot Dash input lines while the current to common is 1 mA or less Paddle outputs can handle voltages up to 50 V and current up to 10 mA 9a5n mail inet hr Nenad Rotter 9A5N 5 Lever sensitivity adjustment The only thing that users can adjust on the Solid State CW Paddle is lever sensitivity to the finger pressure required to close paddle outputs When sensitivity is higher a lower finger pressure is required on the lever to close paddle outputs and vice versa when sensitivity is lower a higher finger pressure is required on the lever to close paddle outputs The sensitivity of lever sides in the single version or levers in twin version are always equal and cannot be changed separately The Solid State CW Paddle has been delivered preset to the highest lever sensitivity This may be too high for some users especially when beginning paddle use and such users may want to reduce it Sensitivity can be adjusted in a range from 10 grams to 50 grams approximately in 8 steps with 5 grams to each step Correct lever sensitivity is very important for correct CW keying and every user should select the sensitivity that is most suitable for him her The Solid State CW Paddle lever sensitivity adjustment is done by a software algorithm and requires no other tools Lever sensitivity can be changed at any time taking just a few seconds When the software algorithm for lever sensitivity adjustmen
