Notice of Discontinuation of Maintenance Support for Doppler Sonar JLN-550

Dear Valued Customer,

Due to the successive discontinuation of production of multiple electronic components used in the JLN-550 over the past several years, we have continued to manufacture service parts by utilizing components available on the open market. However, it has now become no longer feasible to procure such components.

In view of the circumstances described above, it has now become impossible to continue the production of service parts. We therefore regret to inform you that we will discontinue maintenance support for the JLN-550. We sincerely apologize for any inconvenience this may cause and appreciate your understanding.

We would be grateful if you would kindly consider replacing the JLN-550 with our current models listed below. Replacement models: JLN-721 and JLN-740MK2

We greatly appreciate your continued cooperation and support.

Should you have any questions or require additional information, please do not hesitate to contact us.

SHARE THE LOVE
